You are looking at the EBC BSD Rotors. These rotors feature a unique blade slot design which helps remove hot gasses from the braking zone to promote faster cooling for spirited driving conditions. This new slot design helps keep the brake pads flatter and it helps keep the brakes cooler when compared to a traditional uni-directional slotted rotor. 

Like all EBC products, the BSD Rotors are fabricated under strict manufacturing methods and inspected to exact tolerances before getting the green light for customer acquisition. For optimal performance, EBC highly recommends that you use a quality brake pad with this particular rotor. The BSD rotors will work really well with the EBC Greenstuff, Redstuff, Yellowstuff, or even the Bluestuff brake pads. With any of these brake pad choices, the BSD rotors will run cooler with less thermal distortions. 

These particular BSD rotors will be for the rear location, and they will be sold as a pair.
