XYZ Racing Hollow Rear Brake Kit — Audi A1 1.4 TFSI (8X) (2010-2018)

The 8X A1 carries its weight over the front axle and brakes accordingly. Like most front-drive superminis on the PQ25 platform, the rear discs on the 1.4 TFSI are small, lightly worked, and the first thing to wilt once you start stringing corners together on a circuit. The XYZ Racing Hollow Rear Brake Kit gives that under-used rear axle a proper job to do.

This is the rear half of a balanced brake upgrade for the Audi A1 1.4 TFSI (8X), a matched pair of left and right rear calipers and two-piece floating discs built to match a front kit rather than work alone. Larger hollow-vane rear discs and an uprated caliper restore bias to a car that, left standard, throws almost all of its braking effort forward.

What this brake kit does for your 2010-2018 Audi A1 1.4 TFSI (8X)

On the road you will feel a firmer, more confident pedal and a rear axle that helps slow the car instead of trailing along behind it. On track the gains are sharper: the hollow-vane disc core sheds rotating mass, so the rear brakes ride out the repeated heavy stops that cook a standard A1’s back end. Better rear braking also helps the nose-heavy A1 rotate on turn-in, because the rear is finally pulling its weight under load.

Pad compound matches the kit to use. Street keeps daily manners and cold-brake feel intact. Sport adds bite and heat range for spirited road plus the odd track day. Racing holds a steady bite through a full session. The included caliper finishes are Red, Yellow, Gold, Black or Anodized Black, with any Pantone available as a Custom Color.

About the Hollow rear brake kit

XYZ Racing’s Hollow line is built around two-piece floating discs with a hollow-vane core that trims rotating and unsprung mass without surrendering swept area. Less mass at the wheel means the brakes heat and shed temperature more evenly, and the suspension has less inertia to control over kerbs and broken tarmac. The rear kit pairs these discs with an uprated caliper and a choice of three pad compounds – Street for stock-feel daily use, Sport for spirited road and the odd track day, and Racing for sustained track work.

Disc face is drilled or slotted at the same price, and centre bell upgrades, two-tone anodizing in five colours or titanium, are selectable when you order. The caliper is hollow-body as standard, finished in the included colours plus premium polished-forged Titanium, Polished Gold and Polished Silver or candy Teal, Blue, Red and Orange. A Hollow Racing caliper, with no dust cover, a 1000C rating and a two-year warranty, is there for serious track use. It is designed as the rear complement to a front big brake upgrade, returning front-to-rear balance to a platform that leaves the factory heavily biased forward.
