Brembo 09.A198.2S Sport Rear Brake Disc Rotor 316mm Ventilated

The Brembo 09.A198.2S Sport is a rear ventilated brake disc engineered for drivers who demand more than standard OE performance. Part of Brembo's Sport product line, this rotor features a TY3 triple-groove surface pattern designed to improve bite, reduce brake fade, and enhance pedal feel during spirited road driving — all without requiring any vehicle modifications.

Key Features:

• TY3 Triple-Groove Design: Three precision-machined grooves on the braking surface improve initial bite and help evacuate brake dust and gas for consistent, fade-resistant performance
• High Carbon Cast Iron Construction: Elevated carbon metallurgy enhances thermal stability, reduces noise and vibration, and minimizes the risk of distortion or cracking under demanding conditions
• UV Corrosion-Resistant Coating: Solvent-free UV coating protects the full disc surface — including internal ventilation chambers, outer edges, and the hub — against rust and corrosion for lasting appearance and performance
• Pillar Venting Technology (PVT): Brembo's exclusive patented venting design increases airflow through the rotor, delivering up to 40% greater resistance to thermal cracking versus conventional vane systems
• ECE-R90 Homologated: Certified to meet or exceed OEM safety and performance standards with full ECE-R90 type approval
• Direct OE Replacement: No modifications required — installs in place of the original equipment brake disc
• Includes Fixing Hardware: Supplied with a screw kit containing all necessary hardware for straightforward installation
