I have a '92TT with stock springs/shocks. Have to replace the shocks so trying to find best shock. I have 18" wheels and don't want to lower the front any but would love to lower the rear a little. Has anyone replaced just rear springs? I am fine with the ride on touring and would like to keep close to the stock touring ride. Looking at AGX and Bilsteins. Any experience with Bilsteins? Would I get close to stock touring ride with either of these? Any other information is appreciated.
