Wheel width in stock autocross?

rothwem · 01-20-2011, 12:59 PM

My car comes with 17x8" wheels in front, and 17x8.5" in the rear. If I put four rears (17x8.5"s all around) on the car, will I be able to run in the stock class still?

Depends on what organization you're running with and their classing system. For BMW CCA, you'd be fine going wider in the stock class as long as you run tires with at least 140 treadwear.

As far as 2011 scca solo 2 rules go....... No.
Widths and diameter must remain the same.
