i also run at OCRC and WCRC. i start with the team lipo setup and adjust from there, but overall that is a great setup for the car.
one time i had rebuilt/cleaned my whole car and forgot to put back the rear swaybar and for half a pack couldnt figure out why it was so loose and unstable, esp coming out of corners. between that and the weight ballast, that has fixed all my rear traction/"loose" issues.
Can someone post a pic of the weight ballast? I think I need it.
