Fits Mini COOPER (R50) (2002-2006)

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 — Mini COOPER (R50) (2002-2006) — 304 mm
304 mm

The R50 MINI Cooper arrived in Britain with a go-kart reputation that encouraged its owners to brake later and harder than the factory anticipated. That front-wheel-drive architecture, MacPherson struts up front and front-biased weight distribution, concentrates braking load on the front axle every time you tip the car into a corner under deceleration.

The XYZ Racing front brake kit for the Mini COOPER (R50) is built for owners who have found where the standard setup runs out of convincing. It is a single-axle kit: a matched pair of front calipers and two-piece floating discs for the left and right corners. Three pad compounds cover the spectrum from daily-driver improvement through to regular closed-circuit use, across the full 2002 to 2006 model run.

What this brake kit does for your 2002-2006 Mini COOPER (R50)

The front axle on any front-wheel-drive car bears the brunt of braking energy, but the R50’s particular combination of light kerb weight and go-kart chassis balance means drivers routinely ask more of the front brakes than a heavier, more understeer-prone hatchback would. A larger swept friction surface and a stiffer forged caliper translate into harder, more consistent stopping, with the fade resistance to handle back-to-back braking zones on a circuit or repeated hard stops on a fast road. The hollow-vane disc draws air through the rotor body to shed heat between stops, and the two-piece floating disc on its alloy centre bell trims unsprung and rotating mass to keep this light car keen to turn in. Braided stainless lines hold the pedal firm as temperatures rise. Street offers noticeably higher bite than a standard road pad with quiet, low-dust manners and no warm-up period; Sport adds heat range for harder fast-road work; Racing is intended for sustained high-temperature work where road compounds overheat. The chosen caliper finish adds visual presence through the wheels, which matters on a car that invites that kind of attention.

About the Front Brake Kit

This is XYZ Racing’s bolt-on big-brake package for the front axle, pairing an upgraded forged caliper with a larger swept disc area than the production setup. The three-compound system, Street, Sport and Racing, is a key differentiator: rather than a single friction spec straddling road and track, each compound has a defined operating temperature range. The caliper is hollow-bodied as standard, with painted finishes at no extra cost in Red, Yellow, Gold, Black, or Anodized Black, a Custom Color to any Pantone for £150, polished-forged Titanium, Polished Gold and Polished Silver, and candy finishes in Teal, Blue, Red and Orange. Discs come drilled or slotted at the same price, two-tone centre bells in five anodized colours or titanium, and a Hollow Racing upgrade is available for the track, dropping the dust cover, rated to 1000C with a two-year warranty. The kit is a direct replacement for the factory front brake assembly.

Fitment for the Mini COOPER (R50) (2002-2006)

This kit fits the Mini COOPER R50 across the 2002 to 2006 production run. The R50 platform, first-generation BMW-era MINI, uses a shared front suspension architecture across Cooper variants produced in that window. This kit covers the front axle only; rear braking remains stock. The kit includes braided front lines as part of the upgrade, so confirm your existing line setup before fitting if braided lines are already installed.

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.
