StopTech Power Slot Front Rotors for 09-14 WRX - 13+ BRZ / FR-S - 126.47021S

Excessive heat can cause resins in your brake pad to vaporize or "outgas." As the brake pad wears, the used friction material turns into a fine dust. This boundary layer of heat, gas and dust builds up between the pad and rotor surfaces and inhibits performance. Here's where StopTech SportStop slotted brake rotors make a big difference. StopTech SportStop Slotted Brake Rotors are a true performance rotor and feature:

* Power Alloy castings (on select applications)
- Engineered Performance Rotor
- Superior resistance to cracking due to thermal stress
- Increased molybdenum (higher carbon)content that extends reliability, service life and helps reduce NVH noise issues
- Rotor material is a direct descendant of the patented AeroRotor from StopTech

* Introducing directional curve vane design (on select applications)
- Improved vane design or OE equivalent on all rotors
- Center split castings

* New short slot design runs perpendicular to the vane to preserve rotor strength.
* Direct OE Replacement
* Improved wet weather response
* Increased initial bite
* Double disc ground for a consistent friction surface and Improved pad bed-in
* Mill balanced
* Black E-Coated non-friction surfaces on Power Alloy rotors
* Enhances open wheel appearance
