Brembo 08.9488.1S Sport Grooved Rear Brake Disc Rotor

The Brembo 08.9488.1S Sport brake disc is part of Brembo's Cool Line Sport series — engineered for drivers who demand more than OEM performance without sacrificing daily drivability. This solid rear disc rotor features Brembo's signature TY3 groove pattern machined into the braking surface, along with the embossed Brembo logo, delivering a measurable upgrade in braking feel and performance over a standard replacement rotor.

Key Features:

• TY3 Grooved Braking Surface — Proprietary groove geometry improves pad bite, enhances pedal feel, and evacuates heat, gas, and debris from the contact zone for more consistent braking grip
• Improved Fading Resistance — Groove design promotes better thermal management, reducing brake fade during spirited or sports driving
• UV Protective Coating — Full-disc UV coating guards against corrosion on the braking plate, outer edges, and hub, allowing installation straight out of the box with no break-in prep required
• High-Carbon Grey Cast Iron Construction — Minimizes noise and vibration while maximizing thermal stability and disc longevity
• ECE R 90 / UNECE R 90 Certified — Meets European safety and performance homologation standards, confirming OEM-level quality and beyond
• Drop-In Fitment — No modifications required; installs directly in place of the OEM rotor
