StopTech Power Slot 09-10 Audi A4/A4 Quattro / 08-10 A5 / 10 S4 Rear Left Slotted Rotor

If you're looking to improve your Audi's braking performance and appearance, consider this StopTech Power Slot rear left rotor. It's a direct replacement for factory brake systems on a wide range of Audi models, including the A4, A5, and Q5. The unique slotting pattern on this rotor helps to disperse heat and brake dust, which can prevent pad glazing and lead to more consistent braking in both wet and dry conditions. This also contributes to a more responsive initial bite and improved wet weather performance.

Beyond performance, StopTech builds these rotors to last. They feature a black E-coating on the non-friction surfaces to protect against corrosion, keeping them looking good behind your wheels. The high carbon metallurgy, common in many applications, helps reduce noise for quieter operation and offers better resistance to cracking from thermal stress. The rotor surface is double disk ground for a consistent friction surface, and features directional curve vane designs on select applications to further aid in cooling and performance.
