Sharpening the scalpel - 997 GT3 Track Rat

Yep so sway bars are when a large change needs to be made, dampers for smaller changes. I was hoping to be able to make the necessary attitude changes in the damper but it's looking like more of a sway bar change. As the car is feeling nervous on entry I will look to effect a front sway bar change rather than a rear sway bar change, plus I guess having five holes at the front should mean that each change is less acute than the rear's 3 hole setup (based on no actual hard evidence, haha). 

Agree, fine tuning use front, bigger change soften rear

[May 2018]

So I ended up taking the car down to Cascone Autosports as Nick and I both agreed that the clutch issues were probably master or slave cylinder related and I decided to change both, basically something that should have been done with the clutch and flywheel when everything was out at PCM. Anyway after the changeover everything felt great again, positive feel with good pressure.

Had a bit of time before the next event so decided to tidy up some elements of the car; after a decade of wear the original vinyl paint protector things were starting to look a bit manky. One of my mates does wrapping and paint protection stuff so I got him to change the vinyl out to something apparently fancier and also do a ceramic coat paint protection something something...car looks shiny in any case.

As mentioned before my car was originally delivered as a touring spec but the previous owners had some racier stuff installed, however the Velo driver's seat was a bit on the large side, the action on the rail wasn't brilliant and it didn't have provision for the seat-belt buckle so I swapped both seats out for some Bride Vios III Japan FIA. They fit me much better and the aforementioned issues fixed with a rail suited to 986/987/996/997. The suede material is quite nice to sit in and carbon backs add some bling.

Finally, sent my track wheel off to Wheel Solutions to get fixed after going sideways into the turn 3 outside ripple strip at Winton.

Love the BRIDE seats, use to rock a Zeta 2 back in the day... it was so comfortable for a fix back.

I originally ordered Zeta 3 FIAs but there was some concern about the shoulder wings hitting the door card so I decided to play safe with the Vios, the Zeta 3s would have probably cleared but only juuuuuust.

So finally the car is all setup. Clutch feeling sweet and the front swaybar notched up one step harder in an effort to balance the car. The weather is also perfect; chilly morning peaking in the mid 20s by the afternoon and after months of disappointing setup it all finally comes together.

Slowly, slowly I picked up the pace and finally started wailing on the car and it felt better than ever right on the limit. The push-understeer at mid entry is pretty much tuned out and there's nothing but grip to the point I'm not pushing the car hard enough. At the end of the weekend a consistent string of 1:33s with a PB of 1:33.3 puts it back on track. Theoretical PB according the natsoft is around the mid 1.32s so there's something to aim for. The important thing is that the car finally feels sorted and I can start building on things from here, a little tweak of the front dampers in either direction should fine tune things further but for now it's just drive it to find the limits again.

Good to get the setup dialled back in, I know exactly how that feels... I'm pretty much at the same point in development, the last time I was at the SMP GP circuit, the car just felt shit.. last Wakefield outing we spent time on the setup prior, and during, that was rewarding, I hope it feels as good when we return to GP in a few weeks. 

I did sway bar settings too in that last round, I think 1 hole down from hardest at the front and then based on my feedback, Richard Perini recommended that we took the rear one down to the middle setting (it was at the firmest), OEM sway bars still. My complaint was oversteer on exit

I had a 997 GT2 rear sway bar on my 997.1 GT3 it helped the under steer issue that the 997.1 GT3 has.. if anyone is interested in it i would sell it...
