Timm Posted 10April, 2017 Report Share Posted 10April, 2017 Just looking at the pics of that ^ car and noting it is an "early offset" model (ET 23mm) and that it has D90s which have an offset of ~55mm from memory, it appears to me that the wheels are inboard of their correct position, needing spacers to rectify. Or are my eyes deceiving me?You're eyes definitively don't deceive you Rob...you could build a house in those wheel gaps! Didn't all turbo's have the late off-set?The '86 turbo has early offset.

Plugger2 Posted 10April, 2017 Report Share Posted 10April, 2017 Correct Plugger although the fronts are 7.5", i'm not nit picking, just saying that's what they are.I would love a set of Fuchs on my turboSome 86 cars had the late off-set i believe, i'm thinking these would be very late 86 cars, someone correct me if i'm wrong. Didn't all turbo's have the late off-set?If it had the late offset, it would be a MY87, even if built in 86.The 86 Turbos didn't have the late offset (that's why you see them with Fuchs.)

Port 911 Posted 10April, 2017 Author Report Share Posted 10April, 2017 Mine is a 12/86 & has the early offset, would love a set of Fuchs wheels, this would stop the spacer dilemma. Quote Link to comment Share on other sites More sharing options...

That's a very late build date for a MY86 car. Or is that the compliance date?

Buchanan Automotive Posted 10April, 2017 Report Share Posted 10April, 2017 (edited) The 1986 "G" letter in the Vin number 951 is unique , it has different suspension control arms ( narrow track ) like the early series 944 at 23mm & no provision for ABS at all & with the 23mm offset wheels , the wheels at 23mm look mildly dishedThe 1986 951 front stub axles ( Spindles ,USA speak ) were unique to the 1986 model & these cars only ever had the tiny front brakes ( 4 piston Brembo's ) with bolt on front discsThe 1987 "H" letter in the Vin number & onwards to 1995( 968) the suspension arms were changed ( longer ) = wider track , & the wheels have a higher offset number ( much less dish ) & the provision for ABS ( standard on the 951 1987>) & standard on the 944S2 1990>The stub axles ( spindles ,USA speak) were different to the 1986 , along with different alloy hubs & now with slide on front discs , but still the horrible way too small front brakesThe usual 1987 & 1988 Telephone style ( Cast and painted silver) 16" front wheels had a 55mm offsetWith the introduction of the 944 Turbo S( in Europe) in 1988 Porsche changed the front stub axles completely to accommodate radial mounted ( 928S4 type) larger front Brembo brake caliper & the larger 928S4 brake discs With these unique 951 S front stub axles ( spindles) the front wheels had to be 65mm offset ( same as a 928S 1986> / 928S4 etc )These 944 Turbo S models in 1988 & 1989 came standard with the Fuchs Club Sport wheels ( anodised silver finish ) and were ( fronts ) 16" X 7" X 65mm offset ( same wheel offsets and wheel size( SIZE only) as a 928S 1986 / 928S4 > 1991 ) & on the rear the Turbo S had the Club Sport Forged Fuchs wheels in 16" X 9" ( I know as I have two sets my self )The 1990 944 Turbo , be it the M030 ( lets call it the Turbo S version ) did NOT get the expensive Fuchs Forged anodised Fuchs wheels , instead it received the much cheaper to make & buy cast alloy " Design 90 " wheels & its these wheels that had the front rim size of 7.5" X 16" X 65mm off setsNote } The Fuchs Forged and silver anodised Club Sport wheels look ( from a distance ) similar the the much cheaper cast design 90 wheels , particularly if the once beautiful forged /anodised Club Sport Fuchs wheels had been vandalised , meaning painted silver by a vandalThe Fuchs Forged " Club Sport" front wheels only came in 7" X 16 " X 65mm off set = 951 turbo S or 8" X 16" X 60mm offset = 1988CS /SE & 1989 928GT Like the 1990 951 , the 1990 928GT also received the cheaper design 90 cast & painted wheels & these were 7.5" X 16" X 65mm offsetRegardsBruce BuchananBuchanan Automotive Edited 10April, 2017 by Buchanan Automotive flamingporsche and OzJustin 2 Quote Link to comment Share on other sites More sharing options...

Stepo Posted 21April, 2017 Report Share Posted 21April, 2017 For anyone interested, I have just listed my 1990 944S2 on carsales. It's a great car, that's why I bought it, but selling due to the fact I have two S2's and this one needs to go.Price reflects what I paid for the car plus recent costs to attend to issues that needed to be resolved.Here is a link to the ad and some picshttps://www.carsales.com.au/private/details/Porsche-944-1990/SSE-AD-4691916/?Cr=0 MB911, michel, SteveF and 2 others 5 Quote Link to comment Share on other sites More sharing options...
cyberpunky Posted 21April, 2017 Report Share Posted 21April, 2017 If it had the late offset, it would be a MY87, even if built in 86.The 86 Turbos didn't have the late offset (that's why you see them with Fuchs.)The 87 turbo was first with late offset wheels but Australia never got the 87 turbo(with ABS). The 86 turbo was sold for 2 years here and then we got the 88(with ABS and twin airbags). Only relevant if talking Aussie delivered cars. My car was originally purchased in early 87(so is registered as an 87) but I need to order 86 parts for it. Quote Link to comment Share on other sites More sharing options...

I think this car should appeal to anyone who is looking to get in at a slightly lower price level.That Crystal Silver is a really nice colour btw. It strikes me as much deeper and "3D" compared to some of the other Porsche silvers for whatever reason.GLWS.

Buchanan Automotive Posted 22April, 2017 Report Share Posted 22April, 2017 Clarification timeA ) Do not look at the Australian Compliance plate for the year model other than the VIN Letter that gives the "Year Model " , the compliance plate month and year is ONLY when the said Porsche left the bond store at Porsche Cars Australia , remember if any Porsche was not sold to a Porsche dealer the said Porsche just sat in the bond store & the moment ( day ) it was to leave the bond store( car sold) a new stamped ( month & year) Australian Compliance plate was installed onto the said Porsche ( all models sold to the public as a road car ), So it was not uncommon to have a Porsche that sat in the bond store for 6 months or even a year , that means you could have ( example ) a 1986 ( G ) Porsche finally sold 6 months later in 1987 or even later if it was a real unpopular spec configurationVin Letter to year models ( some )A = 1980B = 1981C = 1982D = 1983E = 1984F = 1985G = 1986H = 1987I Not

they were finally imported into Australia ( months later by Porsche Cars Aust ) they were then fitted with Australian Compliance plate because they were purchased new from Porsche Cars AustraliaSame

front , but with the new longer suspension control arms the car received new for 1987 stub axles ( stronger more robust than the small , nearly under-size 1986 951 stub-axles ) & now from 1987 the

Plugger2 Posted 22April, 2017 Report Share Posted 22April, 2017 Small front Brembo brake calipers ( same size caliper & pads as the rear ) = under-braked but very period correct , meaning crap brakes by today's stand were the norm & made worse by the low compression 951 engine , meaning less engine braking , no other brake option available yetClarification time: The Turbos and S2s have always had larger calipers on the front than the rear. Bruce seems to be confusing having the same brake pad size with having the same size calipers.And of course, bigger calipers mean more pressure means more friction (even if the pad sizes are the same). Which all means that 944 brakes are designed pretty much like every other modern car with disc brakes. And hopefully, Bruce might finally get this particular bee out of his bonnet!

Buchanan Automotive Posted 22April, 2017 Report Share Posted 22April, 2017 (edited) Hi Plugger , I am not sure how you could state that , the brake calipers on the early 944 Turbo & the 944S2 & 968 Non M030 are the SAME size front & rear , hence why the brake pads are the SAME size front & rear , just because the brake pistons within the small rear callipers fitted to the front were a little bigger makes very little difference , the brake pads & discs are TOO SMALL for the performance for there vehicle & on a 951 with less engine braking with those small front brakes its bloody dangerous , in fact its that bad that on the 1986 951 ( no ABS ) its very very very common to lock the rear brakes in a brake test at 42 Kmh to do a rego brake test , meaning the car FAILS the brake test & in the wet the 1986 951 with the small front brakes is a dangerous car with worn / old rear tyres , the rears lock up way way too easily , thats because the weight transfer under braking with the SAME size brake pads & same size brake callipers front & rear overwhelms the rear and the rear wheels lock up The best way to fix the 1986 951 rear wheel lock up is to fit the 951 Turbo S ( 928S4 ) front brakes , no more rear wheel lock up in road or track conditions (this is not rocket science ) , its what Porsche did to FIX an issue that was there I repeat , the very small rear brake pads fit the front calipers & visa versa So obviously the brake callipers are the same size front & rear The Brake pads in the Turbo S "much Larger" Brembo brake callipers with its much larger dia and wider front brake discs ( similar to the 928S4 front brake callipers & bigger discs's ) are just that MUCH LARGER & hence the stopping power is much more up to date to put another way the 951 TurboS or the 944S2 M030 or the 968 CS M030 or the 928S 1986 /928S4 front brakes were ( AT LAST ) in their day , way ahead of the pack , meaning the cars would stop with confidence at speed I know you have not owned one with the bigger front brakes & hence why you can not quite come to grips with it & I can to some degree understand what is going on in your mind , if you could experience ( say you're 944S2 ) with the Factory option of the much better front brakes , all will be revealed to you , its quite a different car Hence why it was a FACTORY option ( 951 TurboS front brakes ) on the 944S2 for those customers who knew what it meant , for the others who got the standard small front brakes they just have to put up with crap front brakes and long travel brake pedal ( all very 1980"s crap brakes )Note } the long brake travel is from having to push harder to get the bloody car to pull up with the small front brakes Interestingly Plugger , just last week , Sean upgraded a customers 1990 944S2 to Turbo S front brakes( 928S4 ) at our workshop & the customer who has owner this concourse condition 944S2 for around 20 years can not get over the difference , over the years when he drove it he always complained of the lack of braking as compared to his later model cars he has & boy has it fixed his braking , its now fantastic &to put icing on the cake & not that it needed it, the same 944S2 received a new set of Fuchsfelge ( Fuchs ) forged & anodised 17" X 8 fronts & 17" X 9" rear wheels & continental tyres , just like what I have on my 968 , this 944S2 looks fantastic & now for the first time in its life it stops like a modern car Remember Plugger , the 951 TurboS ( 928S4 ) bigger front brake calipers & Discs & bigger front pads are a FACTORY OPTION when new on the 944S2 / 968 & 951 from 1988 Very Simple stuff & one day you will experience what I mean & finally the light globe will click on for you , until then you are just in the dark RegardsBruce Buchanan Edited 22April, 2017 by Buchanan Automotive Quote Link to comment Share on other sites More sharing options...
Plugger2 Posted 22April, 2017 Report Share Posted 22April, 2017 Hi Plugger , I am not sure how you could state that , the brake calipers on the early 944 Turbo & the 944S2 & 968 Non M030 are the SAME size front & rear , hence why the brake pads are the SAME size front & rear , just because the brake pistons within the small rear callipers fitted to the front were a little bigger makes very little difference[...]I repeat , the very small rear brake pads fit the front calipers & visa versa So obviously the brake callipers are the same size front & rear Bruce, you are obviously still labouring under some basic misconceptions of how brake calipers deliver their force to the brake pads, so let's do a quick recap:The pressure (force) applied to the brake pad is directly proportional to the surface area of the pistons in the caliper. So let's do the arithmetic:'86 951F: 36/38mm calipersR: 28/30mm calipers'87-88 951, non-SF: 36/40mm calipersR: 28/30mm calipersThe combined surface area of the '86 front caliper pistons is therefore ~1.63 times of the rear calipers ((36*36)+(38*38))/(28*28+30*30) = ~1.627, andThe combined surface area of the '87+ front caliper pistons is therefore ~1.72 times of the rear calipers ((36*36)+(40*40))/(28*28+30*30) = ~1.719So the calipers on the front apply between 62-72% *more* force to the front pads (and that is ignoring the effect of the proportioning/brake bias valve.)That is 62-72% more frictional force applied to the frontwheels compared to the rears. Those "small differences" in pistons size actually make all the difference... the front calipers are *significantly* bigger than the rears for all year Turbos. The larger piston sizes are in fact what *make* them "bigger calipers" -- and, contrary to your assertion, the simple fact they use the same size brake pad clearly does not mean "obviously the brake calipers are the same size front & rear." Hope this clears up some basic misconceptions for you and possibly anyone else reading this thread Quote Link to comment Share on other sites More sharing options...
Buchanan Automotive Posted 23April, 2017 Report Share Posted 23April, 2017 Now , lets see Porsche had the larger more effective 944Turbo S ( 928S4) front brakes as an option for the 944S2 / 968 and the 951 from 1988 , I wonder why Porsche did that ? , maybe Porsche thought that putting small rear brake calipers ( size of caliper)& small rear brake pads + small discs on the front was a bit average in the stopping department & so they fixed the problem and as I already mentioned on the 951( 1986-1987/1988 ) with the small front brakes ,meaning the small rear brake pads on the front ( Yikes) , these cars are very non responsive in the brake department & very very NON confidence inspiring , not a good feeling in a Turbo car with little engine braking , but you must already know that or do you ?Remember Plugger ( do you actually have a name ? ) Porsche thought of putting larger /upgraded front brakes on the above cars because it FIXED the poor brakes issueNow lets look at what Porsche learnt in last century cars in regards to brakes that will work with confidence , meaning driving the said last century Porsche beyond 50 % of its performance potential , maybe you might learn something Porsche 928 4.5L ( 1978 - 1980 /81) Auto & manual trans , these cars had the front brakes from the 924 Turbo & these front brakes were tiny little discs & a single piston brake caliber + very tiny front pads & the rear brakes were the same deal , they were the rear brakes from the same car ( 924 Turbo ) even smaller single piston rear caliber & even smaller rear pads Note } the 924 Turbo ( 1979 - 1981) had very period correct brakes , meaning cheap and nasty single piston steel callipers front & rear with tiny brake pads , even the 924 Turbo which weighed less than a 928 didn't stop , but at least it had rear discs brakes where as the 924 NA had even smaller front discs brakes & drums on the rear ( Holy Shit it was bad ), but very early 1970's period correct These ( the 928 1978-1980/81 ) were a very strange car to drive( nice engine and great handling ) but very had poor brakes with manual trans & even worse as an auto trans version , it was so bad that Porsche realised ( more customer complaints than you could poke a stick at in that era ) , yes it was bad even by late 1970's standards that when Porsche released the 4.7L 928S in 1980 , Porsche finally installed bigger front discs & bigger single piston steel caliper which could accommodate a much BIGGER front brake pads that extended outside the normal areas that a normal brake caliber could accommodate in that era , this car finally had BIGGER swept area brake pads & bigger discs , this was a big leap forward , it wasn't the perfect solution , but it was in the right direction to give their customers some confidence in driving these cars ( that were getting faster ) & heavierPorsche in mid 1981 installed the bigger 928S brakes to the 4.5L 928 ( as standard), so the late 1981 & all the 1982 4.5L 928 series( Auto & Man trans) received the 928S brakes ( Big improvement )Note } even without the improved brakes on the 928( 1980> S ) , at no stage did these cars have the tiny rear brake pads & calipers on the front , the front pads & calipers were always BIGGER than the rear , like on every other car manufacturer I can think of Then in 1986 ( G) the 928S then S4/GT ( 1986 - 1991 ) received as standard the same big from discs that the 951 Turbo S finally received & naturally they received the same size Brembo ( large ) 4 piston brake calipers on the front to accomodate the bigger front brake pads ( All Very Simple Stuff to Understand )The small rear Brembo 4 piston brake callipers & pads & discs are the 944S2 /968 / 951 ones & on the back these quite small brake callipers & small rear brake pads are quite suitable for a front engined car "At the rear "928GTS 1992 - 1995 , Porsche made the front Brembo brakes even bigger as standard ( BIG BLACKS ) , larger discs larger Brembo's to accomodate the larger brake pads ( more contact/surface area = MORE stopping power Porsche had finally come of age and very up to date brake performance for a very fast road car in the 1990's You probably do not know Plugger ( is that you're name ? ) , but Porsche struggled with the 964 911 in the brake dept as well( Exact Same Time Period as the 944S2 ) , the first couple of year types ( Australian delivered ) 964 ( 1990 & 1991) had the same brake issues that the 944S2 & early 951 & 968 NON M030 had , meaning the brakes were only good for pottering around with ( just ) & it got worse , when the 964 Tip was released ( meaning Auto Transmission version ) in 1991 , the brakes felt decidedly worse as compared to the manual trans version ( brakes too small ) for the engine performanceThe early versions of the standard 911C2 ( 1990 & 1991 964 ) had the same 944S2 etc small 4 piston Brembo's front & rear brake calipers & naturally the same small brake pads for front brakes , but wait it gets worse for the poor old 964 , on the rear Porsche decided to install much much smaller 2 piston Brembo brake calipers with ( naturally ) even smaller rear brake pads , well didn't this cause some issues , not only did the cars had trouble pulling up ( remember the 964 had quite good performance / acceleration with manual trans ) and these cars at speed & trying to stop in a hurry was a task & the rear brake pad wear was extreme to say the least , basically the extra tiny rear brakes were just overwhelmed The next generation of the 964 ( 1992 - 1994) had 4 piston small rear brake caliper ( 944S2 / 951 / 928S4 etc ) , so it ended up with the same issue as the 944S2 , very average brakes & crap at speed , but at least the rear brakes were fixed on the 964 , remember I am just referring to the stock standard 964 in manual or Auto trans or put another way , the ones they sold the most ofFinally Porsche saw the light ( about bloody time ) and the standard 993 911 ( 1995 - 1998 ) received the 951 Turbo S / 928S4 Brembo front brakes with the corresponding bigger pads & discs , the rear brakes ( pads size & caliper size ) were the good old small Brembo's that first saw the light of day in the rear of the 1986 951 & 1986 928S & front & rear on an early 951 and standard F & R on a 968 So as you can see Plugger , its all about the front brakes , the rears ( except those silly 2 piston motorcycle sized rear ones on the early 964 )were always good Naturally this is all history , Porsche never ever again installed the small rear brake pads on the front & rear of the same car ( any of their cars) ever again So Boxter ( any ) front calipers and pads much bigger than the rears , 996 / 997 / 991/ Cayman etc etc etc all have much bigger front pads and corresponding large calipers than the rears Now Plugger , youre task is to give me/us a list of any brand car/s , be it GM /Ford / Chrysler / Nissan/ Toyota / Mazda / Hyundai / Mercedes / BMW / SAAB / Volvo / Jaguar/ Lamborghini / Ferrari / Maserati etc etc etc , that have the SAME SIZE small rear brake( disc) pads & FRONT & REAR This is going to be a very very short list , I will make it easy for you I will add two car types but its the same brand & same silly sized small front brake pads front & rearA ) Porsche 944S2 / 951 ( early ) & 968 Non M030 & the last version of the 964 911 & yes same pads & caliper size as the rearB ) Can not think of another brand of car ?

Plugger2 Posted 23April, 2017 Report Share Posted 23April, 2017 A ) Porsche 944S2 / 951 ( early ) & 968 Non M030 & the last version of the 964 911 & yes same pads & caliper size as the rear Neither the Turbos nor the S2s ever had the same size calipers front and rear. Sorry if I'm repeating myself, but it does seem like you're just not paying attention. They have the same size brake *pads* front and rear, but significantly bigger *calipers* up front.Resulting of course in significantly more braking force on the front wheels than the rears. (Specifically 62% bigger for the 86 Turbos, and 73% bigger for the 87+ Turbos and S2s.) As you would expect for any rational design for a car with disc brakes.And BTW, just in case this also needs clarification, bigger pads on the same caliper does not result in greater braking force. What it does do is help with heat dissipation and pad wear, though. If you want greater total frictional force, i.e., greater braking force, you need the caliper to apply more force to the pads. And that means bigger total cross-sectional area of the pistons, as explained above. So getting all hung up about the same size brake pads, thinking that means the braking force must be the same, is completely misguided.

Buchanan Automotive Posted 23April, 2017 Report Share Posted 23April, 2017 (edited) Plugger Plugger Plugger , the front brake pads callipers & discs are too small , hence why Porsche finally abandoned this stupid poor braking set up ,thats why the 1988 951 Turbo S & the 968 CS M030 did not use the silly little front pads & silly little discs because they do not work By the way , what is you're name or are you hiding from something ?BBOh , by the way I am waiting for the list of other cars with the same small rear brake pads that were also used on the front , come on Plugger , you can do it Edited 23April, 2017 by Buchanan Automotive Quote Link to comment Share on other sites More sharing options...

cyberpunky Posted 23April, 2017 Report Share Posted 23April, 2017 Thanks for the clarification on the airbags. I wonder if my brakes(86 952) have been modified by a previous owner now, as they are great, and yes I have driven an S2(only everyday for a week) but enough to not feel any day and night difference. I am pretty sure they are stock though *shrugs* Quote Link to comment Share on other sites More sharing options...
michel Posted 23April, 2017 Report Share Posted 23April, 2017 I will buy bigger (928) brakes for my 944t and then look to swap in the 944t gear into the venerable 924twhose got a set up gathering dust .. Quote Link to comment Share on other sites More sharing options...
Rob Posted 28April, 2017 Report Share Posted 28April, 2017 Has everyone gone to sleep? CarSales tells me that the $58k red '86 952 has sold... Only took 5 months. MB911, Port 911 and micknine01 3 Quote Link to comment Share on other sites More sharing options...
Port 911 Posted 28April, 2017 Author Report Share Posted 28April, 2017 (edited) Would be nice to know what it sold for, got to say if I had the money I would have been talking to him myself. It was nice.On another car.924 Carrera GT turbo at $170k, I understand the significance of the car but that is out there. For a car that you are not really going to want to drive. https://www.carsales.com.au/dealer/details/_/OAG-AD-14627296?WT.seg_4=AutoAlert;PCAACollectors only for this one.
