StopTech Drilled Sport Brake Rotor

StopTech Drilled 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 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.

Additional Information

Premium rotor with advanced metallurgy that greatly reduces pad squeal. Especially effective with higher friction; European style brake pad compounds. Slotted for increased bite; improved looks and better performance

Application Summary

2017 - 2020 Toyota 86

Disc Brake Rotor

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 rotors.

SportStop Drilled brake rotors prevent glazing of the pads, add bite and improve wet and dry braking performance.

Every SportStop Drilled brake rotor is produced from a high quality Centric Parts blank casting and finished in a durable e-coating for corrosion resistance.

SportStop Drilled 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 rear replacement rotors is a great way to match the aesthetics of a StopTech Big Brake Kit with the cross-drilled 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 rotors have unique drilled 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 hole never touches a cooling vane.

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only. If you’re unsure about what’s included with this product, please contact our team for clarification.

Reference Information

Cross Drilled Rotor

StopTech drilled rotors offer awesome control, responsive pedal feel, and supreme durability, plus a great look behind your open wheels! These quality replacements fit like your stock rotors, but they're cast from a unique power alloy—chromium and iron—and are mill-balanced to resist thermal stress and vibration noise. Then, they're CNC-machined and drilled to improve heat and gas dissipation and maximize your stopping power. Most have a durable black E-coating applied to the non-friction areas of the rotors to prevent unsightly corrosion for a lasting, sporty appeal. Don't put up with poor factory rotors; you'll run cooler with improved braking performance and an enhanced appearance with StopTech drilled brake rotors.
