XYZ Racing Hollow Rear Brake Kit — Audi A5 8T SPORTBACK QUATTRO (TYPE I) (2011-2016)

The B8-generation A5 hangs its engine longitudinally ahead of the front axle, so the Sportback carries its mass well forward and leans hard on the front brakes to do the stopping. That bias is exactly why the rear axle is worth attention: on a heavy quattro liftback, the back brakes manage load transfer and keep the car settled as you trail the pedal into a turn.

The XYZ Racing Hollow Rear Brake Kit for the Audi A5 8T Sportback Quattro (2011-2016) is built for owners pairing a stronger front setup, or simply correcting the soft, long-travel feel the standard rear gives once the discs get hot. Three pad compounds, Street, Sport and Racing, let one set of hardware cover everything from the commute to a full track day.

What this big brake kit does for your 2011-2016 Audi A5 8T Sportback Quattro

On a 1,600kg-plus all-wheel-drive GT, rear braking does more than the spec sheet suggests, and this is where you feel the change. The two-piece floating disc trims rotating and unsprung mass at the back axle, so the rear responds more crisply and recovers heat faster between hard stops. With the Racing compound fitted, the rear holds its bite through repeated heavy braking instead of going greasy after a few corners, which keeps the quattro chassis stable rather than nose-heavy and nervous under load. Step down to the Sport or Street pad and the same kit settles into quiet, progressive road manners with low dust. Selectable caliper finishes, from the included painted colours through to premium polished and candy options, mean the upgrade reads as deliberate behind the wheels rather than an afterthought.

About the Hollow rear big brake kit

This is a rear-axle kit using a two-piece floating disc, where the vented rotor sheds heat through its core and carries less rotating weight than a solid equivalent. Less mass spinning at the wheel means the rear brake reacts quicker and copes better with the heat soak a heavy AWD car generates on track. The caliper is hollow-bodied as standard to keep weight down, with an optional Hollow Racing build for sustained track use that removes the dust cover, is rated to 1000C and carries a two-year warranty. The kit is supplied with a choice of three pad compounds, Street, Sport and Racing, so the same calipers and discs suit road, fast-road and circuit use without changing the underlying setup. Included painted caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for £150, premium polished-forged finishes in Titanium, Polished Gold and Polished Silver, and candy finishes in Teal, Blue, Red and Orange. Because the hardware is shared across compounds, you can run a quieter Street pad day to day and switch to the Racing compound before a track session, matching the brake to the job rather than the other way round.
