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

This StopTech Power Slot rotor is a direct replacement for your factory rear left brake disc, designed to fit a variety of Audi models including the A4, A5, and Q5. It's built to work with your stock calipers, offering an improved braking experience right out of the box. The unique combination of drilling and slotting is key to its performance, helping to manage heat and brake dust effectively.

The cross-drilling and slotting on this rotor serve multiple purposes. They help evacuate gases and dust that build up between the pad and rotor surface, which can prevent glazing and maintain consistent stopping power. This design also improves initial bite and response, especially noticeable in wet conditions. The rotor itself is constructed with high carbon metallurgy, which is known for offering quieter operation and better resistance to cracking from thermal stress. Plus, the black e-coating on the non-friction surfaces protects against corrosion, keeping your components looking good and performing well over time.

This rotor is a solid option if you're looking to enhance your vehicle's braking performance beyond stock. It's designed to be a direct fit, making installation straightforward when you're ready to replace your worn-out rotors.
