StopTech Slotted Front Pair Brake Rotors 1988-1991 BMW M3 - 126.34023SL/SR - (1991 1990 1989 1988)

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
