XYZ Racing Hollow Rear Brake Kit — Audi A4 B8 QUATTRO (TYPE II) (2011-2015)

The B8 A4’s longitudinal engine sits ahead of the front axle, hanging a disproportionate share of mass over the nose, and that bias shows up hardest under braking, when load piles onto the front discs and the rear axle is left doing comparatively little. This XYZ Racing Hollow Rear Brake Kit for the Audi A4 B8 Quattro (Type II) works on the back of the car directly, restoring rear stopping contribution that the standard setup tends to surrender on a heavy, all-wheel-drive saloon.

It is built for owners running repeated hard stops: fast road, the occasional track day, or simply hauling a fully loaded quattro down from motorway speed. The kit pairs a lightweight two-piece floating disc with a choice of pad compound, so you can match rear bias to how the car is actually driven rather than to a one-size factory specification.

What this brake kit does for your 2011-2015 Audi A4 B8 QUATTRO (TYPE II)

Fit the kit and the first thing you notice is a firmer, more progressive pedal as the rear axle starts carrying its share of the work. The two-piece floating disc trims rotating and unsprung mass at each rear corner, which sharpens how quickly the wheel responds and takes a little edge off the B8’s planted-but-inert factory feel. Three pad compounds let you set rear bite without changing hardware: Street for a daily commute, Sport for harder fast-road driving, and Racing for a hot session. On a quattro that transfers weight forward aggressively, a stronger rear contribution also steadies the car mid-corner under trail braking, where the standard rears can feel overwhelmed. Selectable caliper colours, from the included painted finishes through to premium polished and candy options, let the visible upgrade match the build.

About the Hollow Rear Brake Kit

The rear brake kit is a rear-axle-specific upgrade built around a two-piece floating disc that removes material where it does least for strength and most for weight, cutting rotating mass without surrendering thermal capacity. The caliper is hollow-bodied as standard to keep weight down, with an optional Hollow Racing build for sustained high-temperature work that drops the dust cover, is rated to 1000C and carries a two-year warranty. It is a bolt-on big brake package matched to the B8 A4’s rear hub and hat dimensions, supplied as a complete corner solution, a matched pair of rear calipers and discs with braided lines, rather than a discs-only refresh. Pad compound is specified when you order: Street for road use, Sport for harder fast-road and light-track duty, and Racing for sustained high-temperature work. 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, so the kit reads as a deliberate choice through the wheel. Everything is sized for the rear of the car specifically, which is why the balance shift it delivers stays controlled rather than abrupt.
