XYZ Racing Hollow Rear Brake Kit — Audi S5 8T QUATTRO (TYPE I) (2007-2012)

The 8T S5’s mass sits stubbornly over the front axle, the V8 hung ahead of the wheel centreline and quattro piling driveline weight onto the nose, which is exactly why the rear axle rarely gets the credit it deserves under braking. On a track day or a committed fast-road run, the rears are doing more work than the spec sheet suggests, particularly under trail braking into a long, loaded corner. This XYZ Racing Hollow Rear Brake Kit for the Audi S5 8T Quattro (Type I) gives the back axle the thermal headroom to keep contributing once the standard discs start to glaze.

It is a rear-axle upgrade matched to the way this quattro coupe loads up: larger two-piece floating discs to dump heat and trim unsprung mass, with a forged caliper and pad package you spec to suit your use. For 2007-2012 cars that see repeated heavy stops, it keeps the brake balance honest instead of letting the fronts shoulder everything.

What this big brake kit does for your 2007-2012 Audi S5 8T Quattro (Type I)

Upgrading the rear brakes on a nose-heavy car like the S5 is about stability as much as outright stopping distance. The two-piece floating discs carry more usable thermal mass and shed heat faster, so the rear axle resists fade through a sequence of hard stops rather than giving up early and pushing all the work forward. Choose the Racing pad compound for circuit sessions, the Sport compound for hard road and light track work, or the Street pad for quiet, low-dust feel on the daily commute. Braided lines hold the pedal firm under heat. The payoff is a rear end that stays settled under braking, holds its line on turn-in, and returns a firmer, more repeatable pedal as the discs come up to temperature.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit takes its cue from the disc itself: the two-piece floating rotor’s internal cooling vanes are formed as hollow channels rather than solid pillars, which cuts rotating and unsprung weight while increasing the surface area working against heat. The forged caliper is hollow-bodied as standard. Less mass at the rear corners helps the dampers keep the tyres planted over mid-corner bumps, and the added cooling capacity is what lets the kit hold up where the standard rear setup runs short of thermal room. The discs pair with the caliper and a choice of three pad compounds, Street, Sport and Racing, so the same hardware spans daily duty through to track work. Caliper finishes run Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a custom Pantone option for matching a particular wheel or trim. 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. Everything is sized for the rear axle of this Audi, so it lands as a balanced complement rather than an oversized mismatch.

Confirm your registration year and chassis code before ordering so the rear disc and caliper sizing matches your car.
