My pro street car has the new upper uca's about 3 years ago. (not many miles). Bushings are junk, The nuts just keep loosening up all the time. So I am sick of the stock cheap china junk you get with ALL of these kits. ( I have tried damn near all of them). I was looking at either global west or tcp tubular uppers. For a few bucks more you can get them with the shelby 1"drop option. Any drag guys run the shelby drop? I have a custom coilover front right now and 4 link rear. Race it, and drive it on the street. Thanks much!
