Product Details

This is a set of Wilwood PolyMatrix brake pads, part number 15B-9978K. They are specifically made for Wilwood's W6A and W4A Aero 4 and 6 piston calipers, featuring a .670 inch thickness. These pads are built with the PolyMatrix compound, which is a popular choice for drivers who push their vehicles hard on the track or in demanding conditions where consistent braking performance is critical.

The PolyMatrix compound is known for its ability to handle high temperatures without significant fade, meaning you get reliable stopping power lap after lap. They are designed to provide a strong initial bite and good modulation, allowing for precise control during braking events. While they are built for performance, they are also well-constructed to offer a solid service life under racing conditions.

When installing these pads, remember they are intended for competition or track use. They may produce more dust and noise than a typical street pad. It's always a good idea to consult your caliper manufacturer's installation guide to ensure proper fitment and break-in procedure for optimal performance and longevity.
