I have a 93 Indy Sport, that when the suspension compresses the track rubs on something, I believe the top of the spring coils. The rubber teeth on the inside are not rounded over, they are still very square on all sides, but there is little to no clearance between the spring and the track teeth. It also appears that the top of the rear shock is rubbing slightly on the center of the track. I have tried resetting the track tension several times, using a looser or tighter setting. It didn't seem to make much of a difference. Any help will be greatly appreciated!
