Blake can you give me a little education on spindles's. Whats the advantage from your spindle to the stock C6 Vette spindle I have with my DSE sub? And will your spindles work with the ZR-1 set up. I will have to change my spindles to a ZR-1 spindle. From what I have been reading this must be done do to the 2010 ZR-1 rotors and brakes I'm running.I guess theirs a heat issue that causes the bearing to fail on the stock C6 spindle.. So give me some input!!! I have to have something from Speed Tech on my car
