XYZ Racing Hollow Rear Brake Kit — Ford FOCUS ST (2012-2018)

The Mk3 Focus ST leans hard on its front axle. With a turbocharged EcoBoost lump sitting over the driven wheels and a torsion-beam rear, the standard rear brakes spend most of their life as supporting cast, fine on a B-road but quick to feel out of their depth after three or four hard laps. This XYZ Racing rear big brake kit for the Ford Focus ST (2012-2018) tackles that imbalance head-on.

It adds rear thermal headroom and a firmer, more progressive pedal, giving the back axle enough bite to actually contribute under braking. On a nose-heavy front-driver, that extra rear involvement is what helps the car rotate into a corner under trail braking rather than washing wide at the nose.

What this brake kit does for your 2012-2018 Ford Focus ST

After fitting, the first thing you notice is a pedal that holds up. The hollow-vane discs shed rotating and unsprung mass, so the rear wheels respond faster and the brakes carry less heat soak between stops. On track that means a rear end that stays consistent through a session instead of going soft. Run the Racing pad compound and the kit takes repeated heavy stops from three-figure speeds without the fade you get from the factory rears. The Street compound keeps things quiet and low-dust for daily driving, while Sport sits between the two for fast-road work with the odd track day. Because the back axle now does more of the work, the front discs run cooler too, useful longevity on a chassis that habitually cooks its fronts.

About the Rear Brake Kit

This rear kit is built around a two-piece floating disc with internal hollow vanes that remove material from the rotor structure to cut rotating mass while keeping thermal capacity high. Less mass on the rotating assembly means quicker heat-up and cool-down and less strain on the wheel bearings and hubs. It is supplied as a matched pair for the back axle, with three pad compounds so you can match the friction material to how the car is actually driven: Street for quiet, low-dust road use, Sport for fast-road and the odd track day, and Racing for sustained circuit work. Discs come drilled or slotted at the same price. The hollow-body caliper is standard, with an optional Hollow Racing upgrade for committed track use that loses the dust cover, is rated to 1000C and carries a two-year warranty. Included painted finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a custom Pantone colour at £150, plus premium polished-forged finishes in Titanium, Polished Gold and Polished Silver and candy finishes in Teal, Blue, Red and Orange. It is a bolt-on upgrade that lifts rear braking performance and balance on the Focus ST without re-engineering the rest of the car.
