XYZ Racing Hollow Rear Brake Kit — Audi A3 SPORTBACK 2WD (2004-2013)

The 8P A3 Sportback carries most of its mass over the front axle, and Audi specced the rear brakes to match, with modest discs sized for a car that does the bulk of its stopping up front. The XYZ Racing Hollow Rear Brake Kit for the Audi A3 Sportback 2WD rebalances that equation, giving the rear axle the capacity to keep pulling its weight once the front end is already loaded up.

Few 8P owners stay at standard power for long. The 2.0 TDI and 2.0 TFSI both respond hard to a remap, and the extra pace works the brakes far harder than the factory rear setup was ever meant to handle. This kit hands the rear axle the thermal headroom to cope with repeated heavy stops instead of letting the balance shift forward as the rears wilt.

What this big brake kit does for your 2004-2013 Audi A3 Sportback 2WD

After fitting, the first thing you feel is a firmer, more progressive rear bite under braking. The two-piece floating disc trims rotational and unsprung mass at each rear corner, which sharpens how quickly the A3 settles as you brake into a turn. Three pad compounds let you match the kit to how you actually use the car: the Street pad stays quiet and low-dust for the commute, the Sport pad lifts the fade ceiling for harder road use, and the Racing compound delivers bite that survives session heat if you run track days. Larger, better-cooled rear discs resist the fade that turns a tuned A3’s pedal soft after a few hard stops, so the front-to-rear balance stays where you expect it.

About the Hollow rear brake kit

The rear brake kit pairs a multi-piston caliper with a two-piece floating disc whose internal vane structure sheds weight without surrendering the swept area you need to manage heat. Less mass at the disc means less rotating inertia and lighter loads on the rear hubs and bearings. The caliper is hollow-bodied as standard to keep weight down, with an optional Hollow Racing build for regular circuit use that drops the dust cover, is rated to 1000C and carries a two-year warranty. 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 upgrade reads as deliberate behind the wheel rather than off-the-shelf. Pad choice spans Street, Sport and Racing compounds, covering everything from a road-biased A3 to a car that sees regular circuit time. As a rear-axle kit, a matched pair of rear calipers and discs with braided lines, it works alongside the existing front brakes rather than replacing the whole system, which keeps both cost and installation sensible for what is fundamentally a balance upgrade.

Fitment for the Audi A3 Sportback 2WD (2004-2013)

This kit is built for the 8P-generation Audi A3 Sportback in 2WD (front-wheel-drive) form, across the 2004 to 2013 model years. It is a rear-axle fitment, so confirm your car is the 2WD Sportback and not a quattro before ordering, as the rear hub and caliper mounting differ between the two layouts.
