XYZ Racing Hollow Rear Brake Kit — Audi RS4 B7 AVANT (4WD) (2006-2008)

The B7 RS4 Avant carries its 4.2 FSI V8 ahead of the front axle, and that mass shapes how the car stops. The quattro system’s rear-biased torque split sends drive backwards out of corners, so the rear axle works harder than most owners assume, and the standard rear discs are the first thing to wilt under repeated heavy braking with a loaded estate body behind them. This XYZ Racing Hollow Rear Brake Kit targets that exact weakness.

It is a rear-axle upgrade for the 2006-2008 Audi RS4 B7 Avant, built to hold braking torque through a circuit session that the factory setup starts to give up on. Pad compound is configurable across Street, Sport and Racing, so the kit can be matched to road use or sustained track abuse.

What this brake kit does for your 2006-2008 Audi RS4 B7 Avant (4WD)

On a 1.6-tonne Avant with a high-revving V8, heat is the enemy, and the rear axle’s role in the quattro balance means rear fade shows up as a vague, long pedal exactly when you are trailing into a corner. The Racing pad compound gives you bite that stays consistent as temperatures climb, so the pedal feel you have early in a session is the pedal feel you keep ten laps later. The Sport compound suits fast road and the occasional track day, and the Street compound keeps things quiet and low-dust for everyday driving. Braided lines hold the pedal firm as the fluid heats. Beyond the stopping itself, the forged caliper sits behind the wheel as a visual statement: choose from Red, Yellow, Gold, Black or Anodized Black at no extra cost, or a custom Pantone finish to suit the car. The result on your RS4 B7 Avant is a rear end that resists fade and lets you brake later with confidence.

About the Hollow rear brake kit

The Hollow rear brake kit is XYZ Racing’s rear-axle big brake solution, designed to add thermal capacity and consistent clamping force where the standard RS4 hardware runs out of headroom. The two-piece floating disc and a forged caliper that is hollow-bodied as standard form the backbone of the kit, paired with the pad compound you select: a Street option for quiet, low-dust road driving, a Sport compound tuned for warm, progressive bite in spirited and light-track use, and a Racing compound built to take sustained high-temperature work without shedding friction. Calipers come in five included finishes, Red, Yellow, Gold, Black and Anodized Black, plus a custom Pantone option, so the kit reads as a deliberate fitment rather than an off-the-shelf part. 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 rear-specific, intended to be matched to the front end so braking balance stays predictable rather than throwing bias forward. For a heavy, V8-engined RS4 B7 Avant that earns its keep on track days as well as the road, the priority is repeatable braking, and that is what the compound and caliper options are there to deliver.
