WHAT DO THEY DO?
The RacingLine VWR Rear Disc/Rotor Upgrade replaces the original rear ventilated discs with beautifully engineered motorsport-inspired 2 piece ventilated, grooved discs and aluminium bells (or top hats).
As the dimensions of the original rears are retained (at 310mm x 22mm) this is a simple, direct replacement disc with no other changes needed to rear calipers, pads or mounting hardware.
Not only do the replacement rear discs deliver a better resistance to warping under high heat applications, they also give a small reduction in unsprung mass.
Very simple fit for all A5-platform (Golf 5/6/Scirocco/S3 8P) and MQB (Golf 7 and S3 8V) cars with the larger ventilated rear discs. Bolt on, and drive!
KEY TECH SPECS:
2-Piece Motorsport-Inspired disc conversion to resist warping
Direct replacement for ventilated rear discs, Retaining original rear calipers
Matched appearance to our front Big Brake Kit whilst replacing rusty hubs on the originals
Small but valuable weight-saving over standard
Tested over many thousands of track miles to ensure reliability and performance
/// The VWR Rear Disc Upgrade provides a motorsport-quality direct replacement part developed for our race cars to alleviate the problem of disc warping under high temperatures
/// In common with all top-end motorsport brake applications (including the VWR Big Brake Upgrade Kit), we have selected a two-piece design for our rear discs. Using an aluminium bell (or top hat) bolted to a separate steel disc, the unsprung weight is reduced by around 7%.
/// The ventilated design effectively dissipates heat, while the grooved disc surfaces clear gases released from the pads when hot and help to keep that pad surface clean.
/// Motorsport-specification, highest quality materials and construction
