Fits Mercedes Benz R CLASS 350 V251 (2005-2013)

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.

Painted — includedTell us the exact Pantone (PMS) code you want the calipers painted.Polished forgedCandy
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 — Mercedes Benz R CLASS 350 V251 (2005-2013) — 356 mm
356 mm

The V251 R Class 350 carries more mass than most vehicles in the Mercedes range: a long-wheelbase luxury MPV with a 3.5-litre V6 up front and, in most configurations, 4MATIC permanently engaged. That weight, approaching 2,100 kilograms at the kerb, defines every aspect of the braking requirement.

The XYZ Racing front big brake kit for the Mercedes Benz R Class 350 V251 meets that requirement directly. The front axle carries the dominant deceleration load on any front-engine layout of this scale, and the R350 amplifies that demand every time you pull from motorway speed, descend a long gradient, or arrive at pace with a full cabin. The kit is a matched pair of left and right front calipers and two-piece floating discs, sized to the V251 front hub.

What this brake kit does for your 2005-2013 Mercedes Benz R CLASS 350 V251

The hollow-vane rotor improves airflow through the disc body, drawing heat away from the contact surface more effectively than a standard vented design. For a vehicle of the V251’s kerb weight, that heat management is not incidental: sustained hard applications build temperatures that erode pad bite and pedal confidence on the factory setup. The two-piece floating bell lets the friction ring expand without coning, and reduced rotating mass sharpens response. The three pad compounds let you match the kit to actual use: Street is the quiet, low-dust road default for everyday commuting and motorway work; Sport adds bite and fade resistance for drivers who load the car hard on long runs or mountain roads; Racing is the track compound for the minority who take these capable vehicles onto circuit. Disc faces are offered drilled or slotted at the same price, and the calipers complement the V251’s large-format alloy profiles.

About the Front Brake Kit

The kit is built around a two-piece floating, hollow-vane disc that channels air through the body of the rotor rather than relying solely on surface venting, improving heat rejection under the sustained, high-energy stops a vehicle of the R350’s mass generates repeatedly in normal use. The caliper is hollow-bodied as standard, light and stiff to resist flex, with an optional Hollow Racing upgrade for hard track use that deletes the dust cover, is rated to 1000C, and carries a two-year warranty. Braided lines firm the pedal, and centre bells can be upgraded to two-tone anodizing in five colours or titanium at checkout. Included painted caliper colours are Red, Yellow, Gold, Black, and Anodized Black at no extra cost, with a Custom Color in any Pantone for an additional 150 pounds, plus premium polished-forged and candy finishes built to hold up through the repeated heat cycles any front-axle component must manage on a vehicle of this weight.

Fitment for the Mercedes Benz R CLASS 350 V251 (2005-2013)

This front brake kit is confirmed for the Mercedes Benz R Class 350 on the V251 platform, covering the full production run from 2005 to 2013 and supplied as a left-and-right front pair. Confirm your build date and trim variant against the chassis plate before ordering, particularly for vehicles at the earlier or later ends of the production window where minor specification changes may affect fitment.

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.
