Hi all,

I am bumming as my car has been at the masters for torque tube, tranny and stroker implant since dec and I need to know every ones recommendations on rear tire size. the reason for the build is to have the ultimate open road race vehicle. I am suspecting the best size for power to the ground would be 18x10 carrera's ....does that sound ok.

andy recommendations?

Andy,
I have 18 X 10 et 65 Sport Design with 295/30 X 18's on the rear of my GTS, and they fit great, look fine. They do come out pretty close to the edge of the fender, but there is no interference. I have 18 X 9 et 70 Sport Designs on the front with 255/35 X 18's. Again, no interference, and good tracking/handling.

Another good guy is Andrew Olsen. I have 275's on the rear of my stock 90S4 and they look great.

Hey Roger!

whats the et of the 18x11 and did you cut your spacer down or leave it off?

ROG100

No spacer and I had them made by Kinesis to the right offset.
IIRC I had to change the studs.
I have the documents somewhere. Jim Mayzurk also had a set made for his GTS.

If you still have the stock Cup 1 (C2 Turbo) 17" wheels you can fit up to a 275/40's Michelin Pilot Sport PS2 on them.

These are about as good as you can get on stock 17" - and are in fact pretty good.
