Don`t spent too much time wrenching, just like what I did till now. This hobby is expensive and become even more expensive if it take more of our time wrenching rather than playing ...and in my case, I still have to sell them.

About the front, more negative camber when cornering. You should feel the difference right away. If you use no spacer at all, the dogbone will rubs on front upper arm holder at some point. For the real technical explanation on roll center, nobody beats the pilot, Julius!
