It's not an issue of it being loose. If anything, i have too much grip, and it hooks up too well, causing me to traction roll in some areas of the track. So my tires are fine. I changed my camber last weekend before the main, didn't see how much of a difference it made, due to me breaking a front shock shaft before the race even started.

(totally my fault). I'm not ready to completely start over yet, gonna make a few changes this weekend ( mainly arm sweep, roll centers, and droop). If it's not setup right after that, then i'll consider changing my setup to the one posted above. Buggy feels good in the bumps and jumps, but it seems a bit squirelly in the turns.
btw, what kind of track conditions is the setup above for? I run on an outdoor low-medium traction, bumpy 8th scale track.
