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.
