XYZ Racing Hollow Front Brake Kit — Mercedes Benz R CLASS 350 V251 (2005-2013)

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.
