Upgrade your Audi RS4 B8 with Paragon 2-Piece Front Rotors – a high-performance solution designed to outperform OEM brake discs under aggressive driving and track conditions. These lightweight, slotted rotors improve heat resistance, reduce fade, and save unsprung mass.
Overview
Engineered specifically for the Audi RS4 B8 (8K), these 365mm x 34mm rotors feature a floating 2-piece design with directional vanes for efficient cooling. The high-carbon alloy rotor rings and precision machining deliver consistent performance and longevity, while maintaining full OEM brake system compatibility.
Key Features
- 365 x 34mm 2-piece slotted rotors with directional cooling vanes
- Runs up to 30% cooler than factory rotors – ideal for track or spirited driving
- Fully-floating design allows thermal expansion without distortion
- Rotor rings made from CM-250 high-carbon alloy cast iron
- CBN-machined for optimal pad contact and fast bed-in
- Run-out < 0.03mm and balance tolerance < 2 grams
- Slotted face improves bite, wet braking, and gas evacuation
- Rotor weight: 10.43 kg – 0.68 kg lighter than OEM per side
Construction
Rotor hats are CNC-machined from aerospace-grade 6061-T6 aluminium and MIL-A-8625 Type III hard anodised for long-term corrosion and heat resistance. The design minimises unsprung weight while maintaining strength.
Finish Options
- Clear Hard Anodised: Will not discolour under track heat – ideal for motorsport use
- Black Dyed Hardcoat: May discolour above 260°C – better suited for road use
Vehicle Fitment
- Audi RS4 B8 (8K)
- Model Years: 2012–2015
Fitment Notes
- Direct bolt-on using OEM calipers
- Maintains factory brake bias and ABS functionality
- Compatible with OEM and aftermarket pads (same pad depth)
- Rotor-to-hat mount: H-Bobbin with 10-bolt connection
FAQs
Is this compatible with OEM calipers?
Yes — these rotors are a direct bolt-on fit and work with OEM or aftermarket pads using the same dimensions.
Why choose a 2-piece floating design?
Floating rotors allow thermal expansion under heat without warping, reducing judder and extending component life. They also reduce unsprung weight for improved handling.
Are these suitable for daily driving?
Yes — these rotors are designed for high-performance road use and track days. Choose the clear anodised finish for consistent appearance under repeated high temperatures.
