XYZ Racing Hollow Rear Brake Kit — Bmw X3 F25 (2011-2017)

The F25-generation X3 carries its mass high and well forward, and on a heavy xDrive SUV the rear axle earns its keep on long descents, loaded motorway runs and back-to-back stops where the standard discs run short of thermal headroom. The XYZ Racing rear big brake kit for the Bmw X3 F25 (2011-2017) targets exactly that weakness: a larger, hollow-vane rear setup that puts more thermal mass and a firmer, more progressive pedal behind the back wheels.

This is a rear-axle upgrade aimed at owners who actually lean on the brakes: spirited road driving, the occasional track day, or a fully laden X3 hauling down from speed. It pairs with three pad compounds and a full range of caliper finishes, so the spec follows how you drive rather than forcing a single compromise.

What this brake kit does for your 2011-2017 Bmw X3 F25

After fitting, the clearest change on the F25 is a rear axle that stops protesting under repeated use. The larger hollow-vane discs shed heat faster, and their two-piece floating build keeps each disc true as it heats, so the pedal stays consistent on the third and fourth hard stop instead of going long and soft. With the Racing compound, rear bite is sharp enough to keep the nose-heavy X3 settled into a corner under trail braking; the Sport compound widens the heat range for fast-road and occasional track use; the Street compound trades outright bite for quieter, lower-dust daily manners. Stronger rear thermal capacity also takes load off the fronts, which matters on a heavy AWD SUV pushing close to two tonnes. The net result is more braking confidence on the road and a back axle that holds together when you string corners together.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit is a rear-axle big brake package built around hollow-vane two-piece discs and uprated calipers that replace the standard rear setup on the X3 F25, supplied as a matched left-and-right pair with braided lines. The hollow-vane design opens internal paths that draw heat away from the friction surface while cutting rotating mass, which is what keeps a brake working when a tired stock disc would begin to fade. Caliper clamping is matched to the larger disc, so the added leverage translates into stronger, more linear retardation rather than a grabby on-off response. The kit comes with a choice of three pad compounds, Street, Sport and Racing, letting you bias the system toward quiet road use or sustained hard stops. The caliper is a hollow-body unit as standard, with an optional Hollow Racing version rated to 1000C and a two-year warranty for serious track use. Included painted finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone and premium polished-forged and candy options above that, so the hardware suits the look of the car as well as the job. Discs come drilled or slotted at the same price, and two-tone anodized or titanium centre bells are selectable. Everything is sized for the rear of the F25 specifically, keeping the geometry and clamping appropriate to a heavy AWD platform.
