Do I need to buy two of these rotors?

Yes, brake rotors should always be replaced in pairs on the same axle. This ensures balanced braking performance. You will need one for the rear left and one for the rear right side of your vehicle.

What is the benefit of drilled and slotted rotors?

Drilled holes help to vent heat and reduce weight, while slots help to clear brake dust and gases. Together, they can improve braking consistency and performance, especially under heavy use.

Product Details

When you're looking to restore or improve the braking performance on your 1987-1992 BMW 735i or 735iL, a good set of rear brake rotors makes a difference. This rear left rotor from R1 Concepts features a drilled and slotted design, finished in black, to help your brakes work more effectively.

The drilled holes in this rotor help dissipate heat and reduce weight, while the slots help sweep away dust and gas that can build up between the pad and rotor surface. This combination can lead to more consistent braking, especially during repeated stops. The black finish not only looks sharp but also helps protect the rotor from rust and corrosion, keeping it looking good for longer.

This rotor is designed as a direct replacement for the original part on your specific BMW model, making installation straightforward. Ensure you replace rotors in pairs (left and right) for balanced braking performance.
