Note: Porterfield can custom make any pad from these compounds if a listing is not shown we would need the year make and model. If it is a pad for an after market caliper that we do not show a listing for we would need a tracing of the pad with the length, height, and total thickness (including backing plate) desired. Most pads can be made and shipped on the same day ordered.
