C4S993

2nd day of new SO3s Pole Pos on my '96 C4S. They are quieter than the worn SO2s were. Up front I still have much life left on the SO2s. However, the dealer found a belt out of place on the front right SO2 and I get a sligt vibration at 60+. Also, I have found the "new" rotors to be warped. Do you think I should fix the warped front rotors first before I get new SO3s for up front ?

The dealer informed me that the new SO3s need warming up for aggressive use.

Thanks
