Description

RacingLine VWR B 682001 Stage 3 Rear Brake Rotor Set is the premium two-piece rear-disc upgrade for compatible Volkswagen Group vehicles that already use the factory 310 mm x 22 mm ventilated performance rear brake package. Each rotor combines a high-carbon iron friction ring with a lightweight aluminium centre bell through RacingLine’s fully floating mounting system, reducing unsprung and rotating mass while allowing the hot rotor ring to expand independently from the bell.

RacingLine lists the Stage 3 rotor at approximately 5.5 kg per disc compared with about 7.0 kg for the factory rotor. Removing roughly 1.5 kg from each rear corner helps the damper control the wheel more effectively and reduces rotational inertia. The floating assembly also limits the transfer of heat and mechanical stress into the centre bell, improving stability and consistency during repeated hard stops.

Left- and right-hand discs are individually handed. Directional internal ventilation vanes pump cooling air through the rotor, while the directional triple-groove faces continually refresh the pad surface and provide a visible guide to disc condition. The high-carbon friction rings are selected for thermal stability, and the precision-machined aluminium bells deliver the motorsport-derived construction and purposeful appearance expected of RacingLine’s Stage 3 hardware.

• Matched left- and right-hand rear axle set

• Approximately 5.5 kg per rotor versus about 7.0 kg factory weight
• High-carbon iron friction rings and lightweight aluminium bells
• Directional internal cooling vanes
• Directional triple-groove faces help clean the pad surface
• Direct replacement for factory 310 x 22 mm ventilated rear discs
• Exact RacingLine part number: VWR B 682001 / VWR682001

Fitment is determined by the rear brake hardware, not the model badge alone. These rotors directly replace the factory 310 mm x 22 mm ventilated rear discs. Vehicles supplied with the smaller 300 mm x 12 mm solid rear rotor require the complete genuine larger-caliper conversion before either disc set can be used. Check the original rotor dimensions, brake PR code and caliper specification before ordering.

Driving benefit: Stage 3 is aimed at drivers who value reduced unsprung mass, improved thermal behaviour and sharper brake consistency on fast road and track. It retains the standard compatible caliper position and rotor dimensions, so the upgrade concentrates on disc construction rather than changing rear brake bias.

Installation: braking components are safety-critical. Professional installation is recommended. Confirm that the supplied handed discs are installed on the correct side, inspect calipers and pads, clean hub faces, measure runout, use the correct torque procedure and complete the prescribed bedding-in cycle. Replace worn or contaminated pads and use suitable high-temperature brake fluid for sustained performance driving.
