996 GT3 Posted 15August, 2017 Report Share Posted 15August, 2017 Looking to choose R-SPEC tyres for my 996 GT3. 235/40 -18 & 295/30 - 18Only doing club level track days, not full circuit racing or Targa rallies. Will use my R-specs on a dedicated set of BBS rims, leaving road tires on my standard rims. Some say the Yokohama A050 is the ultimate and obviously its top dollar. What do people think is the best “bang for your bucks” value option? including from the following:-Yokohama A050 vs AD08 vs V105 -Dunlop DZ03G -Hankook z221-Kumho V70a-Toyo R888-Others? Appreciated and regards to all Link to comment Share on other sites More sharing options...
hugh Posted 15August, 2017 Report Share Posted 15August, 2017 +1 on the A050's as the goods if your just building a second set of wheels for th track. AD08's if you want the best of both worlds. My 2 cents. Link to comment Share on other sites More sharing options...
James P Posted 15August, 2017 Report Share Posted 15August, 2017 Yokohama A050 & the Hankook Z221 are very close in lap times for the same compounds i have used both on a 997 GT3 & can't tell the difference, i would go the Hankook's for sure Link to comment Share on other sites More sharing options...
Redracn Posted 15August, 2017 Report Share Posted 15August, 2017 AO50, Z221, DZ03G all great tyres and I wouldn't bother with any of the others for track only work on 18'sFor price performance I would take the Z221AD08, PSC2 and the like are not in the same league but there are plenty of threads already on this topic.

DJM Posted 15August, 2017 Report Share Posted 15August, 2017 Peter Fitzgerald was adamant GT3s work best on A050s. Mechanic for my RX7 track car is adamant his IPRA RX7 works best on A050sive used them ever since, they've been awesome Link to comment Share on other sites More sharing options...
Robert930 Posted 15August, 2017 Report Share Posted 15August, 2017 +1 for A050, but identical grip in the Z221 at a cheaper buy inIf your only doing a few laps at a time (3-4) then try Softs on the front and Mediums on the back, seems to be the magic combo Link to comment Share on other sites More sharing options...
rego Posted 15August, 2017 Report Share Posted 15August, 2017 I've done a few sets of some of these tyres on different cars, my thoughts on each of the tyres I've tried is below:Z221 Soft - These are perfect if you do short stint ‘club style’ track days as they can be pretty much warmed up during the out lap. The compound seems to be somewhere in between an A050 Soft and A050 Medium. #1 bang for buck but they won't suit if you do longer sessions or are running in hotter weatherA050 Soft - These tyres are quick but I wore through them like butter on my Evo, they may work on a lighter car but on my MX5 race car I never ran them and instead just went with Z221 softs as they are not that much slower and Z221 Softs seem to wear a bit better.Z221 Medium - These are suited if you ever go to track days where they offer longer 10-15 minute sessions and plan to stay out for a while. #1 bang for buck but softs will be faster if you only ever do shorter sessions.A050 Medium - These are great all around tyres and seem to be marginally quicker than the Z221 Mediums but the reality with any race tyre is that you only really have 1 track day (arguably less) to do the ultimate time anyway as after that they will fall off so if you aren’t super competitive I wouldn’t bother paying the extra $ for these.R888 - Spend the extra money on a proper tyre.Hankook have a good guide which shows the temperature range for their tyres as well as optimum ground temperatures if you are interested in using that to determine your choice of compound http://www.competitiontyres.net.au/wp-content/uploads/2013/04/Hankook-Handbook.pdf (Page 4, Compound Information) Link to comment Share on other sites More sharing options...
edgy Posted 16August, 2017 Report Share Posted 16August, 2017 I'm running the A050 soft on my gt3, its only run on club super sprint days, were the sessions are about 8 mins, they are great once you got the pressures dialled in, consistent, loads of grip, and they behave well once you reach the limit of adhesion, its a nice linear break away, they don't "snap out".R888's I ran, wasn't fussed on The Hankook I have heard lots of good things about, so when the A050's are toast, I may be compelled to try some Link to comment Share on other sites More sharing options...

Snowman Posted 17August, 2017 Report Share Posted 17August, 2017 last time I checked the USA didn't have the good R-comps.They only have the R888's and Nitto's, It's why most of them use the Hoosier R7's as much as possible. Link to comment Share on other sites More sharing options...
Jason A Posted 17August, 2017 Report Share Posted 17August, 2017 Yokies are the pick, soft on front and hard on the rear. They will be 1 - 2 seconds faster that anything on your list.Be careful with US compound. I have been told only Japan and select few countries get the good compound. Aus gets the better compound. Is to do with time attack - maybe it has changed now, that was 12 months ago.No affiliation to Yokies, just my opinion. Link to comment Share on other sites More sharing options...
