  • Gas-slotting improves cooling
  • Anti-corrosion e-coating

How do I order?
Most people buy a set of left and right rotors for their Mustang. However, due to accidents or other circumstances, you might occasionally need only a left or right rotor. Choose from the available selections listed above.

StopTech Sport rotors were formerly sold under the PowerSlot brand name. Part numbers: 8182PSL and 8182PSR.

  • Direct replacement brake rotors for the Mustang stock brake system.
  • Improves cooling! StopTech rotors feature slotting that sloughs off the hot gases and debris that form between the pad and the disc. This action also adds more bite.
  • Looks great behind custom wheels.
  • Improved appearance. Helps your Mustang's rear brakes match the aesthetics of a StopTech front big brake kit.
  • Rotor finish prevents pad glazing and improves wet and dry braking performance.
  • Excellent corrosion protection on non-swept surfaces provided by e-coating.
  • 1-piece design.
  • Gas slots.
  • Durable black e-coating on the non-swept areas of the rotor (both sides of the hat, inside the cooling vanes, and on the outside edge).
  • Direct replacement of stock rotors.

What is "e-coating"?
E-coating is a superior, electrostatically applied finish designed to withstand 400 hours of salt water exposure without rusting. This is especially important on both mounting faces of the hat: where it touches the hub flange and the back face of the wheel. Any accumulation of rust in these areas can lead to installed lateral run-out issues.
