StopTech Brake Rotors - SportStop Slotted: 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:

• 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 
• 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
