of a '90 LX coupe... My buddy has a '90 LX coupe with a 4 link rear suspension, no quad shocks, solid lower, adjustable upper control arms... he is trying to figure out how big he can go... he's looking at a set of 17X10.5" /03 Cobra rims... if you guys could just let me know what the largest rim size you can run on the rear, and also the largest tire... that would be awesome.
