Description
The Hawk Performance® HB664Z.634 is a Performance Ceramic (Z compound) street brake pad set for the front or rear axle, depending on the vehicle, of the 2006-2017 Porsche 911, Porsche Boxster and Porsche Cayman as listed below, supplied as one axle set (2-wheel set) of pads in the HB664 shape at 0.634 in thickness.
IMPORTANT: Hawk Performance® lists this part number for the front or rear axle, as shown, of the vehicles in the fitment table below, by model, year and trim. Where a trim is listed only for vehicles built through a certain date, or only with certain equipment, that limit is shown in the last column. Where Hawk Performance® qualifies a trim by brake package, it is listed for vehicles without ceramic composite brakes. Trims and years not shown are not listed by Hawk Performance® for this part number; confirm your vehicle against this list before ordering. These pads are not compatible with carbon ceramic (ceramic composite) rotors; Hawk Performance® specifies these pads for use with iron rotors only; do not install them on vehicles equipped with carbon ceramic brakes. This listing is the Performance Ceramic (Z) compound only. Other compounds of the HB664 shape are sold separately: HB664G.634 (DTC-60, race only); HB664B.634 (HPS 5.0, high performance street). Sold as one axle set (2-wheel set).
