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

The B8.5-generation S5 carries its supercharged 3.0 TFSI V6 well forward of the front axle, and that nose-heavy quattro layout means the rear brakes spend most of their working life balancing the car rather than scrubbing off the bulk of the speed. The XYZ Racing Hollow Rear Brake Kit for the Audi S5 8.5T Quattro (Type II) is built to keep that rear axle settled when the fronts are loaded hardest: under repeated hard stops, on long downhill braking zones, and during sustained fast-road and track work.

This is a rear-axle kit, so its job is composure and consistency rather than headline stopping numbers. With a choice of Street, Sport and Racing pad compounds, and a full set of caliper finishes, it lets you match the rear of the car to how you actually drive the S5.

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

On a heavy, four-wheel-drive coupe like this, the standard rear brakes can heat-soak before the fronts have given their all, which is what nudges the pedal long on a third or fourth hard stop. This kit restores rear bite and pedal consistency as temperatures climb, so braking stability holds under trail-braking into a corner. The Racing pad compound suits repeat track sessions, the Sport compound suits hard road and light track use, and the Street compound keeps cold-bite manners and low dust for daily use without squeal dominating the commute. Braided lines hold the pedal firm under heat. Paired with a front upgrade, it also keeps front-and-rear balance honest rather than overloading the nose.

About the Hollow rear brake kit

The Hollow rear brake kit takes a weight-conscious approach to the rotating assembly, using a two-piece floating disc to trim mass at the rear hubs where unsprung and rotational weight matter to ride and response. The forged caliper is hollow-bodied as standard. The kit is configurable around three pad compounds, Street for quiet road use, Sport for spirited fast-road driving and light track, and Racing for track temperatures, so the friction material can be matched to the duty cycle rather than compromised across all of them. Caliper finishes are offered in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a custom Pantone option, letting the rear calipers read as a subtle factory-look upgrade or a deliberate statement behind the wheels. Braided lines are included, discs come drilled or slotted at the same price, and the centre bell can be upgraded to two-tone anodized in five colours or titanium. It is engineered as a direct-fit rear-axle solution for this chassis, not a universal part adapted to suit.
