Fitment & Compatibility
This four-piston AERO4-ST package is a road-racing conversion with BP-35 high-temperature pads and Thermlock pistons. The table below separates Corvette C5/C6 and Cadillac XLR applications from older GM vehicles that require the listed Ridetech hub spindle. Factory early-GM spindles are not interchangeable with that aftermarket interface. Dynamic lug-drive hats carry the directional GT rotors. Select the flexline kit for the actual year and spindle arrangement; hoses are not included. Sustained low-temperature operation of racing pads accelerates rotor and pad wear.
