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 Allo rotors
Enhances open wheel appearance
WARNING: This product can expose you to chemicals, which is known to the State of California to Cause Cancer, Birth Defects, And Other Reproductive Harm.
