Hawk Performance part HB926C.577 places the HPX motorsports compound on that front axle, pairing clean modulation with smooth initial bite in the 100 to 600 degree F range where autocross and club racing events typically operate. HB926C.577 is a direct-fit replacement for the factory Brembo front caliper hardware on the Z51 and carries Hawk Performance's limited lifetime warranty.
