XYZ Racing Hollow Rear Brake Kit — Audi S5 8.5T 2WD (TYPE II) (2013-2017)

The B8.5 S5 carries its mass hard over the front axle, which means the rear brakes spend most of a session managing balance rather than scrubbing off the bulk of the speed, and that is exactly where a heavy supercharged GT coupe gets caught out under repeated heavy stops. The XYZ Racing Hollow Rear Brake Kit for the Audi S5 8.5T 2WD (type II) adds thermal headroom and a firmer, more predictable pedal at the back axle of a car that works its brakes harder than its grand-tourer manners suggest.

This is rear-axle hardware aimed at fast-road and circuit use on the 2013-2017 S5. The two-piece floating disc trims rotating mass at each rear corner, and three pad compounds let you match the bite to how hard you actually drive.

What this brake kit does for your 2013-2017 Audi S5 8.5T 2WD (TYPE II)

Fit it and the first thing you feel is consistency: the rears stop wilting after three or four big stops from speed, so the S5’s balance stays settled instead of the nose washing wide as the back axle overheats. The two-piece floating discs cut rotational and unsprung mass behind each rear wheel, which sharpens how quickly that corner reacts to load and takes a little strain off the dampers. Run the Racing compound for firm, repeatable bite on track, the Sport compound for hard road and light track work, or the Street compound to stay quiet and clean for daily miles. Braided lines hold the pedal firm under heat. Across all of them the pedal sits high and progressive, which is what gives you the confidence to brake later into a turn.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit swaps the standard S5 rear setup for larger two-piece floating discs and forged calipers sized to shed heat faster than the factory parts. The caliper is hollow-bodied as standard, and machining mass out of the disc casting lowers rotating weight without giving up swept area, so you keep thermal capacity while reducing the load each wheel carries. Three pad compounds span the range of use, Street for quiet road manners, Sport for harder fast-road work, and Racing for sustained circuit abuse. Calipers are offered in five included finishes, Red, Yellow, Gold, Black and Anodized Black, with a custom Pantone option, so the kit can hide behind the wheels or read as part of the build. Braided lines are included, discs come drilled or slotted at the same price, and the centre bell upgrades to two-tone anodized in five colours or titanium. It is built as a balanced rear complement to a front big brake upgrade, keeping brake bias sensible on a front-heavy coupe.

Fitment for the Audi S5 8.5T 2WD (TYPE II) (2013-2017)

This kit is cut specifically for the Audi S5 8.5T 2WD (type II) built from 2013 to 2017, the B8.5 facelift coupe in two-wheel-drive form. It mounts to the rear axle as a pair of rear calipers and discs, designed around that chassis’s hub and caliper geometry. Confirm your exact build year and rear hub before ordering so the disc and bracket spacing line up.
