Fitment & Compatibility

Direct listed front applications include Corvette C5/C6 for 1997–2013 and Cadillac XLR for 2004–2009, with each trim/year condition retained in the table. The older listed GM vehicles, spanning selected 1962–1982 applications, require the stated Ridetech hub-spindle conversion; those entries do not establish stock-spindle compatibility. Six-piston AERO6 calipers work with 14.00 × 1.25-inch Spec37 rotors and separate hats. Slotted versions use BP-20 pads, drilled-and-slotted versions BP-10. Flexlines are separate: 220-8176 is the C5 front reference and 220-9100 the C6 front reference; the 220-12168 reference for converted applications must be checked against the actual chassis, ends and routing. Confirm the hub interface and the wheel drawing, using 18 inches only as minimum diameter guidance.
