Get the most out you Porsche with our factory German, Cross Drilled Brake Rotors. Unlike stock rotors that are drilled here in the States, our rotors are Cast with holes already in them during the manufacturing process. This process leaves smooth, convex tapered holes that will not excessively eat away at your expensive brake pads. Ambient mass also plays a big roll in your cars handling characteristics. Our Cross Drilled Rotors are up to 5% lighter than their stock counter parts, enabling for quicker, crisper turning through the twisties!
