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

The B8.5 S5 carries its supercharged 3.0 V6 well ahead of the front axle, so the brakes that do the hard work live at the front and the rear pair tends to coast as the junior partner. On a fast road run that arrangement is fine; string together hard stops on a track day and the standard rear setup is the first to fade, glaze and start to muddy the car’s balance.

This XYZ Racing Hollow Rear Brake Kit for the Audi S5 8.5T 2WD (type I) gives the rear axle the thermal headroom to keep pulling its weight. More consistent rear torque means the car settles earlier into a corner and stays composed when you brake deep, rather than leaning entirely on a front end that is already loaded.

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

You feel the change as a firmer, more progressive rear bite that does not drop off after repeated stops. With three pad compounds to choose from, Street, Sport and Racing, you can match the rear to how you actually use the car, from daily commuting to a full circuit session. A better balanced bias front and rear sharpens turn-in and reduces the nervous, nose-led braking the B8.5 platform can show when the rears are tired. The two-piece floating disc trims rotating and unsprung mass at the rear, which helps both pedal feel and the way the suspension follows the road, and braided lines keep the pedal firm under heat.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit pairs a forged caliper with a two-piece floating disc engineered to shed heat faster and resist fade under repeat loading. The caliper is hollow-bodied as standard, and cutting mass from the disc reduces the rotating inertia at each rear wheel, so the brakes respond more cleanly and the unsprung weight the dampers have to control comes down. The three-stage pad range, Street, Sport and Racing, lets you tune outright bite and temperature window to your use case rather than accepting a single factory compromise. Calipers are offered in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a custom Pantone finish, so the visual change behind the wheels matches the mechanical one. 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.
