Stoptech Slotted Rotor Front Left - 345mm - Audi A6/A7/Q5/S4/S5 | 126.33138SL

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
