The changes we made today were the rear spring, machined pistons, and changing the ballstud washers from kit settings. We started with a slight cross between kit and Truhe's setup.

Like RCMayor said, the back end rolls a lot on kit springs and really locks it in. Cush was looking for more steering in the middle of the corner; changing the springs and removing the ballstud washers let it rotate more naturally, but also gained exit traction. Its pretty surprising how well it puts down power.
