What size are the wheels on your blue car? Do you happen to know the offset and/or weight?
Thay are 15" rims with 225/50-15 on the rear and 195/50-15 on the front. I think I'll go to a 195/45-15 in the front next to get a little more clearance. I had to modify the front of the front fenders to allow them to turn inward on the front side of the wheel. I don't remember the offsets, but I'll see if I can find the paperwork and get back to ya. I also replaced the final drive to a 454:1 ratio so the drive would be close to the same. And it'll be a lower drive when I put the 13" rims on at the track! The weight was VERY light. They are Keizer racing rims. I think they were somewhere around 8-10lbs. I'll get back to you on the offsets.
