PARAGON 2-Piece Rear Rotors Audi S4 / S5 / SQ5 (B9/B9.5) 330 x 22mm

Enhance rear braking performance on your Audi S4, S5, or SQ5 B9 / B9.5 with Paragon 2-Piece Rear Rotors. Designed for serious track and street use, these 330mm x 22mm lightweight rotors improve heat dissipation, reduce fade, and cut unsprung weight — all with direct bolt-on fitment and full OEM system compatibility.

Overview

These rotors use directional ventilation vanes to guide airflow through the core, reducing temperatures by up to 30% under load. The floating 2-piece design accommodates thermal expansion without warping, keeping the rotor centred with the pads and delivering consistent bite under repeated hard braking. Slotted surfaces clear debris and water, improving wet-weather braking stability.

Key Features

• 330 x 22mm slotted rear rotors with directional cooling vanes
• Up to 30% improved cooling vs OEM – reduced fade and heat soak
• Floating 2-piece design allows expansion while maintaining alignment
