I just did the frame mod's to fit 315's. My setup is pin drive IRS with standard front arms. What backspacing works the best. I will be running 17's. Also how wide for front and back. Pictures would be great if anyone has any. Thanks in advance. :D

Mark,

The Compomotive measurements for the wheels I ordered are:
Rear 17" X 11" w/4.5" Backspacing
Front 17" X 9" w/6" Backspacing

This is what I used with the Pin drive rear and 315s.

Tires are Dunlop SP Sport 8000
Rear 315/35/17
Front 275/40/17

Later

sorry no pictures. Thanks Jeff for the info I am going to try to order my wheels this week. I'm going to be using PSE wheels. The backspacing should be the same.

Thanks David. I know your help is going to be invaluable to me durring my build. I'm curious are you running 6" bs in front as well. Also are you running 275's on front in street trim or on track only?
