XYZ Racing Hollow Rear Brake Kit — Bmw X2 F39 (2018-2023)

The X2 F39 sits on BMW’s transverse UKL platform, nose-heavy and taller than the hatch it shares its bones with, which loads the front axle hard and leaves the rear doing quiet but important work under braking. The XYZ Racing Hollow Rear Brake Kit goes straight at that rear axle, adding thermal headroom and a more consistent pedal to a crossover that weighs more than its compact footprint suggests.

Think of this as the rear half of a balanced upgrade. On a front-biased X2, the rear brakes set stability into a corner under trail braking and stop the fronts from carrying the whole car alone on a long descent or a track session. Specify it alongside the matching front kit and you keep the bias where BMW intended, with more capacity at both ends.

What this brake kit does for your 2018-2023 BMW X2 F39

After fitting, the first thing you feel on the X2 F39 is a firmer, more progressive pedal that does not go long once the discs are hot. The hollow-vane disc trims rotational and unsprung mass at the rear, which helps the rear suspension settle over broken UK B-roads, while the two-piece floating build keeps each disc true as it heats. Pad choice sets the character: the Street compound keeps daily refinement and low dust, the Sport compound adds bite and a wider heat range for fast-road work, and the Racing compound holds friction through repeat heavy stops on circuit. On a heavier xDrive or M35i car, that extra rear capacity is what keeps brake balance predictable across a full track session.

About the Hollow rear brake kit

The Hollow rear brake kit is built around XYZ Racing’s lightened rear disc, a two-piece design where the hollowed internal vanes shed mass without giving up the swept area needed to manage heat. It mounts to the X2 F39’s rear hubs as a matched left-and-right pair, with braided lines, replacing the factory discs and calipers directly. Three pad compounds cover the spread of use: Street for everyday low-dust driving, Sport for spirited road use and a wider temperature window, and Racing for track days. 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 rear hardware reads cleanly through the wheel spokes. Discs come drilled or slotted at the same price, and two-tone anodized or titanium centre bells are selectable. The kit’s priority is thermal stability and a repeatable bite rather than raw initial grab, which is exactly what a road-and-track crossover wants at the rear.

Fitment for the BMW X2 F39 (2018-2023)

This kit is specified for the BMW X2 F39 across the 2018 to 2023 model years, spanning the sDrive and xDrive variants on that chassis. It fits the rear axle as a direct-fit upgrade over the standard discs and calipers. Confirm your exact build year and rear wheel clearance before ordering, since caliper size sets the minimum wheel diameter.
