Having my Z for almost 2 years now,I am getting around to doing some mods. Right now, this is my daily driver. What can I change to get rid of the bounce that the suspension has? I also want to buy new wheels.I want to put 20's on. My 1st choice would be the ROJA Formula 55's. I do noteven know if these are available yet.My second choice is Axix Se7en Mods. With the Axis wheels,is it true that you can't have a BBK ?
