Running 315/35's on all four corners

[todesengel]

Anyone do this? I just bought a set of ccw's (17x12) to run all the way around, and was curious what the consensus was for running the 315/35/17's on the street.

You are not indicating what offset these wheels are. Nonetheless, extra width in front could either make the wheel and tires project out too far beyond the wheel well or rub against the fender skirt when wheels are turned all the way right or left - or both.
Also, due to extra width/grip in the front relative to factory intent, you could introduce oversteer.
Please understand that I am no suspension engineer - just my thoughts.

well Dan at ccw has done a couple of these before, and knew what I wanted. I will get the exact offset from him tomorrow.

I've seen several c4's run that combo on the road track with good handling results'. I was going to buy a set a while back and tried mine on the front just to see how it looked, but didn't like the way they stuck out with the 36mm offset. Not sure, but I think the ones at the track were not the 36mm on the front.

I can't wait to see pics and hear of the result.

These might stick out some (maybe an inch on the sides up front).


Go with 10's on the front 285 / 40 / 17 and 12's in the rear 335 / 35 / 17.

They will rub when you try to turn.

Won't stick out, won't rub. CCW knows their stuff!

These are 17x11 fronts, 17x12 rears.

I have run 315's on all 4 corners on the track with correct offset wheels. Worked fine except tough on power steering at very low speed.

Yup, It can be done.

Here is Ed (FastZR1) with 315s all the way around.
