Im running 255/40/17 on volk 9" rear with CTSC 7psi and loose traction in first gear some times. Might go slightly wider.

 

Spoolin and Courage, how would you compare your handling to a stock S?

 

The handling seems to be as good as stock if not a bit better. Although, in corners with DR's on the back at 18-20 psi tire pressure, the rear feels a little mushy but not too bad. If the tire pressure is around 28-30 psi on the rears, it doesnt even feel like a DR on the back in corners. There is a fine balance of tire pressure that is needed for the rears for decent cornering on DR's and good grip for the power. If I am doing more straight line driving and for all out power, I leave the tires at 18-20 psi but if I know beforehand that there will be some cornering with what I'm out doing, I'll put the tire pressure up around 28-30 psi to help the rear DR's in cornering and still have good grip.

Hope this helps.

 

I don't know yet. I am still finishing building the car. I will be done within the next couple weeks so I'll let you know then...and when it warms up a bit around here. The car will be run at Miller Motorsports Park for a number of events this season. I'm hoping she's got epic handling so I can put some pressure on some of the exotics that come out now and again.
