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:

• **These are sold individually. Order two per axle.
• Power Alloy Castings - 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
• 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.
• 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
