StopTech Power Slot Front Left Sportstop for 00-05 Legacy / 98-08 Impreza

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 Alloy” rotors * Enhances open wheel appearance
