What is the benefit of drilled and slotted rotors?

Drilled holes help vent heat and gases away from the brake pad and rotor surface, reducing brake fade. The slots also help to keep the rotor surface clean and can improve wet braking performance.

Does this rotor come with any hardware?

This product includes one rear left drilled and slotted black brake rotor. Hardware such as lug nuts or brake pads are typically sold separately.

How should I maintain this black finish?

The black finish is designed to resist corrosion. Regular cleaning with a brake cleaner and a soft brush will help maintain its appearance and performance.

About this part

Product Details

You're getting one rear left drilled and slotted black brake rotor from R1 Concepts for your 2004-2009 Audi S4. This rotor is designed to replace the stock one on the driver's side rear of your vehicle, helping to ensure consistent braking performance.

The drilled holes in this rotor help to dissipate heat and expel gases and moisture from the braking surface. This means you get a more reliable stop, especially during repeated hard braking. The slots also help to keep the rotor surface clean and reduce brake fade. The black finish isn't just for looks; it helps protect the rotor from rust and corrosion, keeping it looking good and performing well for longer.
