These spacers include mounting bolts to mount the spacer to your hub. Your existing Ferrari bolts are then used to mount the wheel to the spacer.

We strongly encourage you to inspect the condition of your existing wheel bolts whenever a wheel is removed and refitted, for whatever reason. If the threads appear damaged or compromised in anyway, please consider purchase of new bolts. Our Ferrari bolts from Hill Engineering are of the highest quality, and "priced right".  See item SLWB01 for more information.
