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

Product Overview

For drivers who need something even tougher than a standard StopTech Sport rotor, but are not ready for a big brake kit, StopTech offers cryogenically treated Cryo rotors.

Cryogenic treatment is a one-time stress relief process that involves both cold and heat cycling of the brake rotor. Using a proprietary computer-controlled process over a 24-hour period, the cryo machine gradually cools the rotors down to -300 º F, then gradually brings them up to over +300º F, and finally back to room temperature. This conditioning of the rotor improves its service life, especially in fleet and emergency vehicle applications.

Any new StopTech or Centric Premium 1-piece replacement rotor can by cryogenically treated prior to shipment. Cryo treatment typically adds 5-7 business days for processing.

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.
