XYZ Racing Hollow Rear Brake Kit — Bmw X4 F26 (2014-2018)

The F26 X4 carries close to 1.8 tonnes on a raised, coupe-SUV body, and most of that mass wants to keep moving the moment you lift off the throttle. That is exactly when the rear axle has to earn its keep. The XYZ Racing Hollow Rear Brake Kit gives the back of the X4 the clamping force and thermal headroom to do its share of the stopping, instead of leaving the front brakes to cook on a long descent or a sequence of hard B-road stops.

This is the rear half of a big brake conversion, sized for a heavy xDrive crossover that punishes standard pads on repeated heavy braking. The hollow-vane disc trims rotating and unsprung mass at each rear corner, and the kit is offered with a choice of pad compound so you can match the rear axle to how the car is actually driven.

What this brake kit does for your 2014-2018 BMW X4 F26

On the road you notice it first as a firmer, more progressive pedal: the rear contributes earlier, so brake balance shifts rearward and the nose dives less under heavy stops. For a vehicle as tall and heavy as the X4 F26, that steadier platform means more confidence trail-braking into a roundabout or scrubbing speed before a motorway slip road. The hollow-vane discs cut rotating mass and their two-piece floating build keeps each disc true as it heats, which sharpens initial bite and eases the load the rear suspension has to manage. Spec the Racing compound and the rear axle keeps grabbing through repeat stops where a tired OEM pad would start to glaze; the Sport compound widens the heat range for fast-road use, while the Street compound stays cleaner, quieter and low-dust for daily duty.

About the Hollow rear brake kit

XYZ Racing builds this as a dedicated rear kit rather than a one-size bracket, so the caliper and disc suit the X4’s rear hub and parking-brake arrangement, supplied as a matched left-and-right pair with braided lines. The hollow name refers to the disc design: material is removed from the internal vanes to lower the rotating mass of each disc, which helps the brakes shed heat and reduces the gyroscopic effort the rear suspension has to deal with. Three pad compounds are offered, Street for quiet, low-dust use, Sport for stronger fast-road bite and a wider heat range, and Racing for repeated hard use and track work. Each compound trades differently between cold performance, noise and outright fade resistance, so the kit can be specced for a daily X4 F26 or a car that sees the occasional circuit session. 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. Discs come drilled or slotted at the same price, and two-tone anodized or titanium centre bells are selectable.

Fitment for the BMW X4 F26 (2014-2018)

This kit is cut for the first-generation X4, chassis code F26, covering the 2014 to 2018 model years. It fits the rear axle specifically and is designed to work with the factory rear hub and parking-brake setup on that platform.
