Does this rotor come with hardware?

How many rotors do I need to order for the rear axle?

This listing is for a single rear left brake rotor. For a complete rear axle brake job, you will need to order two rotors to ensure balanced braking performance.

What is the benefit of the black E-coating?

The black E-coating on this rotor provides a layer of protection against rust and corrosion. This helps maintain the rotor's appearance and prevents premature wear, especially in areas exposed to moisture or salt.

Product Details

If you're looking to improve the stopping power on your classic rear-wheel-drive GM coupe, this R1 Concepts drilled and slotted brake rotor is a solid option. Designed for vehicles like the Buick Reatta, Cadillac Eldorado, and Oldsmobile Toronado, it's built to handle the demands of spirited driving and frequent braking.

This rotor features a black E-coating that not only gives it a clean, finished look but also helps protect it from rust and corrosion, especially important for vehicles that might sit for periods. The drilled holes help vent gases and heat away from the braking surface, while the slots sweep away dust and moisture. This combination means you get more consistent braking performance, especially during repeated stops or in wet conditions. It's a well-built rotor that offers a noticeable improvement over standard, plain rotors.

This rotor is sold individually, so be sure to order two for a complete rear axle replacement. It's a direct fit for the specified vehicles, making installation straightforward for anyone comfortable working on their car's brakes.
