Paragon 2-Piece Rear Brake Rotor Pair - VW Golf GTI Mk8 / Golf R Mk8 / Audi S3 8Y / RS3 8Y (Larger Rotor) - 355x22mm

Paragon 2-Piece Rear Rotors deliver a significant upgrade in cooling, strength, and braking stability for the MQB Evo platform. Designed as a direct bolt-on solution, these 355mm x 22mm rotors improve thermal performance, reduce unsprung mass, and maintain full compatibility with OEM ABS and brake systems.

Overview

Directional ventilation vanes improve airflow through the rotor core, lowering temperatures by up to 30% under repeated heavy braking. The floating 2-piece design allows the rotor ring to expand and contract with heat while staying aligned with the pads, reducing fade and maintaining braking consistency. Upgrading from the OEM 310mm to a 355mm diameter improves brake torque and heat capacity without compromising fitment.

Key Features

• 355 x 22mm slotted rear rotors – replaces factory 310mm setup
• Floating 2-piece design allows thermal expansion and self-alignment
• CM-250 high-carbon alloy rotor rings – heat-treated and CBN-machined
• Directional vanes improve cooling by up to 30%
• Lateral run-out ≤ 0.03mm; balanced to within 2 grams
• Slotted surface improves pad contact and wet-weather braking
• Rotor-to-hat mount: D-Bobbin (Short), 10-bolt system
• Each rotor weighs 6.12 kg – saves 0.68 kg per side vs OEM

Construction

Rotor hats are CNC-machined from aerospace-grade 6061-T6 aluminium and MIL-A-8625 Type III hard anodised for maximum corrosion and heat resistance. Weight is reduced through strategic material removal while preserving high-load strength.

Finish Options

• Clear Hard Anodised: Will not discolour under sustained track temperatures – ideal for motorsport use
• Black Dyed Hardcoat: May discolour above 260°C – better suited for street applications

Performance Benefits

• Increased rotor size improves brake torque and fade resistance
• Reduces thermal deformation and brake judder under load
• Slotted face enhances pad bite and clears gases or water
• Reduced unsprung weight improves handling and ride control

Vehicle Fitment

• VW Golf GTI Mk8
• VW Golf R Mk8
• Audi S3 8Y
• Audi RS3 8Y
• Only applicable to vehicles with factory larger rotor package

Fitment Notes

• Direct bolt-on fit – no modifications required
• Maintains factory brake bias and full ABS integration
• Compatible with OEM or aftermarket brake pads (same pad depth)
