Fitment & Compatibility

For the listed 2004–2006 Pontiac GTO front applications, retaining the original hubs. The six-piston dust-sealed Superlite calipers use BP-10 pads and 14.00 × 1.25-inch rotors. Follow DS-1296's distinct sleeve and shim arrangement for 2004 mounting, along with the required original hard-line positioning and ABS-wire bracket relocation. Front hose kit 220-14177 is included even though hoses are not visible in the supplied laid-out photograph. The hat's 5 × 4.72-inch mounting pattern and clearance holes are dimensional references, not a stud-thread specification. Check the actual wheel with the drawing; 18 inches is minimum diameter guidance, not automatic clearance.

Listed models: GTO. See the supplied table below for each year, submodel and equipment condition.
