SportStop rotors are 1-piece drilled and slotted rotors from StopTech made specificly for your BMW E90/E92. They are direct replacement discs for your E90/E92 factory brake system and stock calipers. They offer improved cooling as well as other advantages the competition doesn't offer.
Cross-drilling helps wipe away the debris that forms between the pad and the disc, adds more bite, and can help the rear brakes to match the aesthetics of a front big brake kit. The rotor finish helps prevent glazing of the pads and improves wet and dry braking performance. Additionally, SportStop rotors feature a durable black e-coating on the non-swept areas of the rotor to prevent corrosion.
StopTech rotors are sold individually, a left and right rotor are required for a complete axle set.
