Description

StopTech Drilled and Slotted Sport Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers that look great behind your wheels – and offer significantly improved braking performance. The unique cross-drilling and slotting aids with heat and brake dust dispersal; prevents glazing of the pads; adds bite and improves wet and dry braking performance. Built to last; the black e-coating provides protection from corrosion and the high carbon metallurgy (in most applications) offers quieter operation; better crack resistance and increased performance.

Product Overview

StopTech recognizes that great brakes need to look as good as they perform. Performance wheels and tires are best complemented with StopTech SportStop Cross-Drilled & Slotted rotors. SportStop Drilled & Slotted brake rotors prevent glazing of the pads, add bite and improve wet and dry braking performance. Every SportStop Drilled & Slotted brake rotor is produced from a high quality Centric Parts blank casting and finished in a durable e-coating for corrosion resistance. SportStop Drilled & Slotted rotors look great behind custom wheels, improve the initial bite of the brake pads, and help wipe away the debris that forms between the pad and the disc. A set of SportStop cross-Drilled & Slotted rear replacement rotors is a great way to match the aesthetics of a StopTech Big Brake Kit with the cross-Drilled & Slotted rotor option. *E-Coated Finish* Every SportStop rotor is finished with black e-coating on both sides of the hat, inside the the cooling vanes, and on the outside edge. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. This is especially important on both mounting faces of the hat where it touches the hub flange and back face of the wheel. Any accumulation of rust in these area can lead to installed lateral run out issues. *Power Alloy Metallurgy* Power Alloy metallurgy is exclusive feature of SportStop rotors. In specific vehicle applications, StopTech works with foundry partners to increase the molybdenum or carbon content of the castings, and to carefully control the cooling rate during production to reach targets for hardness and tensile strength. *Cooling Vane Design* Nearly all SportStop Cross-Drilled & Slotted rotors have unique Drilled & Slotted hole patterns for the left and right sides of the vehicle. For these directional patterns, straight vane or pillar vane rotors are used to ensure that a Drilled & Slotted hole never touches a cooling vane.
