For aftermarket suspension they check the serial number of the springs and shocks and the numbers from the TUF approval must be entered into the vehicle registration card.

I'm surprised the shocks are stock. There must be a lot of tuning potential there if they are valved for softer springs. Is it common for 986 racers to tune their shock absorbers?
