The O2 cars are a little different. If they get squirly (loose) on the brakes, raising the rear end and/or lowering the front (Creating rake) can settle them down. If they get squirly on throttle, raising the front/lowering the rear can help. Also reducing wheel rate (spring) in the back or reducing the rear sway bar can help with loose on throttle. Some of them already have those settings maxxed though, so.. Bout the only thing I touch with these cars is tire pressure. Not even sure that makes much difference, but sidekick gives me the +/- "delta to ideal" so I usually follow that.
