Fits Bmw 1 SERIES F 21 (2011-2019)

Brake pad compound

Street: quiet, low-dust, strong cold bite for road driving. Sport: higher temperature range and more bite for fast road and occasional track. Racing: maximum fade resistance for sustained track use (noisier and dustier cold). Match the pad to how hard you actually brake.

Disc size

Caliper grade

Hollow is the standard caliper: a lighter hollow-body forged caliper with a dust cover and a 5-year warranty. Hollow Racing drops the dust cover for sustained high-temperature use (rated to 1000°C, 2-year warranty) — the track-grade choice.

Caliper colour

Painted colours are included. Polished-forged finishes are mirror-polished forged calipers (Titanium, Gold, Silver); candy colours are a deep, mirror-reflection paint. Both are premium upgrades — fuller detail further down the page.

Disc style

Drilled discs (cross-drilled holes) vent gas and water and look aggressive; slotted discs (surface grooves) wipe the pad face clean and resist fade under sustained hard use. Same price — choose on looks or how you drive.

Centre bell

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. Standard anodized is included; a two-tone bell adds an anodized accent ring in your choice of colour; titanium is the lightest, forged option.

Carbon-ceramic rotor

Carbon-ceramic rotors are a special-order track upgrade: far lighter than steel, fade-resistant at extreme temperatures and extremely long-lived. The price follows the disc size you choose above. The standard two-piece steel rotor is included.

XYZ Racing Hollow Front Brake Kit — Bmw 1 SERIES F 21 (2011-2019) — 356 mm
356 mm

The F21 1 Series is built around one of BMW’s last genuinely rear-wheel-drive small-car platforms, and that layout shapes how the front axle performs the moment serious braking loads arrive. Weight transfers rearward naturally on corner exit, but into a heavy braking zone, particularly with M135i or M140i variants relying on front friction to scrub 300-plus brake horsepower, standard brake components reach their thermal limits quickly. The XYZ Racing Hollow front brake kit for the 2011-2019 BMW 1 Series F21 addresses the front axle directly.

It is a single-axle front kit, supplying a matched pair of front calipers and front discs. Three pad compounds, Street, Sport and Racing, cover the range from daily commuting through spirited road use to full circuit sessions without a kit change between applications. Caliper finishes run from the included painted colours of Red, Yellow, Gold, Black and Anodized Black at no extra cost through to premium options, and at this level of specification they sit visibly inside the F21’s alloys, as they should.

What this brake kit does for your 2011-2019 Bmw 1 SERIES F 21

The F21’s near-50/50 weight distribution is what makes the chassis so rewarding at the limit, but that balance depends on the front brakes working consistently when the nose is loaded hard under deceleration. Fade from insufficient thermal capacity narrows the braking window before the tyres or the chassis are actually spent; confidence drops, braking points creep earlier, and the rear-drive balance becomes harder to exploit. The hollow-vane, two-piece floating discs do the thermal work, and the floating construction keeps pad contact even as the rotor expands.

The Hollow kit’s three compounds let you match friction characteristics to session type: Street is the quiet, low-dust default for daily use, Sport gives progressive bite and heat range on fast roads, and Racing is for track-day environments. Discs come drilled or slotted at the same price. The front-axle focus reflects where braking loads concentrate on the RWD platform: under hard deceleration, weight transfers forward, loading the front tyres and asking the most of the front calipers and discs.

About the Hollow Brake Kit

XYZ Racing’s Hollow series targets drivers who have worked through what the factory braking system can offer and want a defined step up without committing to a full motorsport conversion. The caliper is hollow-bodied as standard, paring mass from the corner while preserving clamping force.

Caliper finish covers the included painted colours of Red, Yellow, Gold, Black and Anodized Black at no extra cost, plus Custom Color in any Pantone and premium polished-forged or candy options, so the kit sits alongside whatever alloy and bodywork combination the buyer has already specced, without a visual clash. Disc style is drilled or slotted at the same price, and pad compound choice is made at order, so the correct friction grade for the car’s primary use is fitted from the first drive rather than requiring an immediate change. Centre bell upgrades in two-tone anodized colours or titanium are selectable at checkout, alongside braided lines. For serious track use, the optional Hollow Racing caliper upgrade runs without a dust cover, is rated to 1000C and carries a two-year warranty. The kit covers the front axle, the position that handles the dominant share of braking load in the F21’s rear-wheel-drive layout, particularly during the hard initial deceleration phase.

Fitment for the Bmw 1 SERIES F 21 (2011-2019)

This kit covers the F21 generation BMW 1 Series, the three-door hatchback body style, produced from 2011 through to the end of production in 2019. The F21 shared its front suspension geometry across the engine range, from 116i to M140i, so the kit applies to both petrol and diesel variants within those years. Confirm your trim designation against SKU XYZ-BRK-BKF-BM-01-H-FRONT before ordering.

Choosing your spec

Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.

Brake pads — Street, Sport or Racing

Every kit ships with a full set of high-performance pads; the compound is your call.

Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.

Caliper grade — Hollow vs Hollow Racing

Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.

Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 286–380mm (front). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.

Caliper colour & finish

Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).

Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.

Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).

Centre bells

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
