Re: 4th gen what fits
Ok, most drag wheels for the 4th Gen F-Body requires a heavy dose of caliper grinding. I ground down my calipers to fit the Weld Pro Stars. 15x3.5(front) 15x10(rear). The 15x3.5s require less grinding than the 15x4s. The 15x8s and 15x10s are about the same. 15x3.5 is a 1.75BS, 15x8 is a 5.5BS and 15x10 is 7.5BS for proper fitment. There are companies like Bogart and Billet Specialties that offer a specialized wheel to fit 4th Gens with no modification but they are much higher than anything else. You can also grind alittle on the calipers and run a spacer, IE: 5/16th is the most common. Greg Weld was developing a affordable wheel to fit 4th Gens but went out of business only after they got the front to fit without having the grind the caliper. Billet Specialties has a wheel that'll fit the rear without grinding but have not yet come out with a front yet. You can also check if Centerline to see what they offer. As far as tires go, most run the 165-15 "VW" tire on the front as it's the stock height, 26in, and Mickey Thompson ET Street Radial, 275-50-15 for the rear, for the same reason as the front and it's the widest tire you can get on there without rubbing. If you have anymore questions, just let me know and I'll be glad to help.
