Fits Bmw 1 SERIES E 81 123 (2007-2012)

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 E 81 123 (2007-2012) — 304 mm
304 mm

The E81 123d sits in a niche almost no other manufacturer attempted: a high-torque twin-turbo diesel in a three-door hatchback, rear-wheel drive when every rival was channelling power through the front axle. That combination is compelling on a B-road and demanding on a circuit; the torque bites hard on corner exit, weight transfer under braking is pronounced, and the front axle carries the work of hauling the car from speed repeatedly across a session. Standard braking equipment was built for normal use; this kit is not.

The XYZ Racing Hollow Front Big Brake Kit for the BMW 1 Series E81 123 addresses the gap between factory specification and consistent fast-road or circuit performance. It is a single-axle front kit, supplying a matched pair of front calipers and front discs. Three pad compounds, Street, Sport and Racing, let you match the setup to what the car actually does, rather than running a single compound that suits neither commuting nor track sessions particularly well.

What this brake kit does for your 2007-2012 Bmw 1 SERIES E 81 123

The hollow-vane, two-piece floating disc dissipates heat more aggressively than a standard vented rotor, which has a direct effect on the front braking of a worked E81 123. The combination of a heavy nose, substantial torque, and rear-wheel-drive weight transfer concentrates sustained load on the front axle across repeated braking zones, exactly where standard equipment begins to feel soft. The floating construction keeps pad contact even as the rotor expands with temperature.

The Racing compound shifts the fade threshold noticeably higher and keeps pedal feel consistent through back-to-back laps; the Sport compound suits a 123 that covers motorway miles Monday to Friday and a track session a month; the Street compound is the quiet, low-dust road default. Discs come drilled or slotted at the same price. Caliper finish runs from the included painted colours of Red, Yellow, Gold, Black and Anodized Black at no extra cost, through Custom Color in any Pantone, to premium polished-forged and candy options, giving the kit visual definition behind the wheels.

About the Hollow Front Brake Kit

The caliper is hollow-bodied as standard, paring mass from the corner while preserving clamping force, and the disc’s internal geometry expands the thermal surface area available for heat dissipation, the two factors that most directly affect braking consistency under repeated high-load conditions. Three pad compounds span the full operational range from standard road use through spirited fast-road driving to circuit and competition running, so the same disc and caliper combination can be respecced as the car’s use evolves rather than requiring a full swap.

Disc style is drilled or slotted at the same price, and caliper finish covers the included painted colours of Red, Yellow, Gold, Black and Anodized Black at no extra cost, alongside Custom Color in any Pantone and premium polished-forged or candy options for builds with specific colour requirements. 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 front fitment targets the axle carrying the majority of braking work on the E81’s rear-wheel-drive platform.

Fitment for the Bmw 1 SERIES E 81 123 (2007-2012)

This kit is specified for the BMW 1 Series E81 three-door hatchback in 123 trim, covering the full production run from 2007 through to 2012. The E81 body code distinguishes the three-door from the E87 five-door variant; confirm your chassis code before ordering, as the fitment is specific to the E81 123 and not interchangeable across the wider 1 Series range.

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.
