Now to the problem. I have polished thin spokes on stock stagger - 17" front, 18" rears. I want to keep these wheels. Yes I like them and will keep them. I want stealth for the street as well as the strip. The car will do occasional duty at the local 1/8 mile drag. I will be fitting drag radials to what ever rear rims I use. I will be keeping the 17" fronts but I have access to another set of 17" thin spoke fronts that could be widened for duty on the rear.

I think it about $250 per rim to widen. Is the 17" rims worth the cost in terms of traction and tire availability or should I just say good enough and run the origial 18's
