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. Heres 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
