PARAGON 2-Piece Rear Rotors Audi S4 / S5 / Q5 / SQ5 (B8/B8.5) 330 x 22mm

Upgrade the rear braking system on your Audi B8 or B8.5 platform with Paragon 2-Piece Rear Rotors. These lightweight 2-piece rotors are designed for track and performance driving, offering improved heat management, consistent braking response, and a significant reduction in unsprung mass — all with full compatibility to OEM systems.

Overview

Each rotor features directional cooling vanes that draw air through the disc, reducing rotor temperatures by up to 30% under aggressive use. The floating 2-piece design allows for thermal expansion without warping or pad misalignment. Slotted faces improve wet-weather bite, clear debris, and deliver consistent performance during repeated high-load stops.

Key Features

• Direct replacement 2-piece slotted rear rotors
• Floating design for thermal expansion and stable pad alignment
• CM-250 high-carbon cast iron rings – heat-treated and CBN-machined
• Directional vanes improve cooling efficiency up to 30% over OEM
• Precision balanced to within 2 grams; run-out ≤ 0.03mm
• Slotted surface increases pad bite and performance in wet conditions
• Rotor-to-hat mounting: D-Bobbin (Short) 10-bolt system
• Each rotor weighs 5.53 kg – saves 2.02 kg per corner vs OEM

Construction

Rotor hats are CNC-machined from aerospace-grade 6061-T6 aluminium and MIL-A-8625 Type III hard anodised. The lightweight design reduces unsprung mass while retaining structural integrity for repeated high-heat use on track or street.

Finish Options

• Clear Hard Anodised: Will not discolour under track heat – best for motorsport use
• Black Dyed Hardcoat: May discolour above 260°C – recommended for street use
