About this part

Product Details

The .670 inch thickness of these Wilwood PolyMatrix A brake pads means they offer a substantial amount of friction material for extended use. These pads are specifically designed for Wilwood's AERO 4 and AERO 6 brake systems, providing a direct fit for those popular caliper setups. They are built with Wilwood's PolyMatrix compound, a well-known friction material that balances street drivability with track performance.

Wilwood developed the PolyMatrix compound to offer improved stopping power and consistent performance across a wider temperature range than standard organic pads. This makes them a solid option if you push your vehicle hard, whether on spirited drives or occasional track days. The material is formulated to provide a strong initial bite and good modulation, allowing for precise control of your braking. They are a well-built choice for drivers looking for an upgrade over stock pads in performance calipers.
