When replacing your STaSIS(tm)/Alcon rotors, you should also replace the hardware at the same time. Stasis had several versions of the hardware so you will need to identify which hardware you have in order to order the correct kit. Hardware replacement is generally good practice for any brake system, street and especially track. However, in the case of the STaSIS assemblies, the disc springs have a tendency to flatten with age. The fine threads in the nut & bolt are often compromised upon removal due to corrosion
