XYZ Racing Hollow Front Brake Kit — Bmw X1 E84 (2009-2015)

Built on the E90 3 Series floorpan but carrying the body mass of a crossover, the E84 X1 asks more of its front brakes than its SUV classification suggests. xDrive variants, which account for most of the E84s spec’d with any performance intent, carry roughly 120kg more than their sDrive counterparts, and all of that weight pushes forward under hard braking. Over a spirited mountain route or a track day in a late-spec M Sport, the factory front setup begins to show its limits: pedal creep, fade on repeated use, and a softness under load that does not match what the chassis can actually handle.

The XYZ Racing Hollow front brake kit covers the full E84 generation from 2009 to 2015. It is a single-axle kit, a matched pair of front calipers and two-piece floating front discs for the left and right corners. Three pad compounds, Street, Sport and Racing, let owners tune the system to how the car is actually driven, with a wide caliper colour range for those who want the upgrade visible through 17in or 18in open-spoke alloys.

What this brake kit does for your 2009-2015 Bmw X1 E84

The hollow-vane front discs shed heat faster than the OEM solid rotors the E84 left the factory with, reducing the sustained fade that becomes noticeable on the sDrive 20i or 25i when driven hard across a flowing B-road, and the two-piece floating construction keeps the rotor flat against the pad as it expands. On xDrive models, where the extra drivetrain mass amplifies front-axle load under braking, the larger rotor diameter improves the mechanical advantage at the caliper, giving shorter stopping distances for less pedal effort. Brake balance loads the front hardest under heavy stops, so this is where the upgrade matters most, and dropping rotating and unsprung mass there sharpens turn-in. The three compounds mean you are not forced to run a track pad on a car that also covers the daily commute: spec Street for regular use, move to Sport for weekend drives with the odd lap, or step up to Racing if the E84 is doing track sessions. Included painted caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone available, so the installation can complement or contrast with the body colour as it shows through the wheel.

About the Hollow Front Brake Kit

XYZ Racing’s hollow-vane discs use an internal vane geometry that channels air through the rotor body during rotation, targeting the heat accumulation that causes pad glazing and fluid boil under repeated hard stops, paired with a two-piece floating construction that grows cleanly under load. The kit is built for the front axle specifically, the heaviest-loaded position on any front-engined crossover and the point where the E84’s mass first arrives during braking. The caliper body is hollow-cast as standard, with an optional Hollow Racing caliper, no dust cover, a 1000C rating and a two-year warranty, for serious track use. Three pad compounds cover the full operating envelope: Street for relaxed urban duty, Sport for spirited road use, and Racing for sustained high-load driving, all running the same caliper and disc hardware so moving between compounds is a pad swap rather than a rebuild. Included painted finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for £150 and premium polished-forged Titanium, Polished Gold and Polished Silver plus candy Teal, Blue, Red and Orange. Discs come drilled or slotted at the same price, and centre bells can be two-tone anodized in five colours or titanium.

Fitment for the Bmw X1 E84 (2009-2015)

This kit is built to the E84 X1 front axle specification and covers all engine and drivetrain variants across the 2009 to 2015 production run, including both sDrive and xDrive configurations. The E84 chassis code identifies the first-generation X1 on the E90 3 Series platform; if your car’s build plate shows E84, this kit fits. Confirm your existing front rotor diameter and bolt pattern before ordering if non-standard wheel fitment or brake spacers have been applied at any point.
