XYZ Racing Hollow Rear Brake Kit — Mercedes Benz C CLASS W204 C 300 4MATIC (2007-2014)

The W204 C 300 4MATIC is a heavy executive saloon that carries its all-wheel-drive hardware over the front axle, and Mercedes specified the rear brakes for comfortable road use rather than sustained heat. The XYZ Racing Hollow Rear Brake Kit addresses that directly, fitting larger, lighter two-piece floating discs with hollow vanes and an upgraded caliper to the back of the car so the rear axle pulls its weight when you start braking hard from speed.

This is the rear half of a balanced upgrade, supplied as a matched pair of rear calipers and discs, for owners running the C 300 4MATIC beyond its everyday brief – quick A-road work, the occasional track day, or simply restoring confident stopping to a car that weighs the better part of 1.7 tonnes. Pad compound choices run from Street through Sport to Racing, so the kit suits a daily driver as readily as one that sees circuit time.

What this brake kit does for your 2007-2014 Mercedes Benz C Class W204 C 300 4matic

The first change you feel on the W204 is brake feel under repeated stops. The larger rear discs add thermal mass, so the pedal stays firm where the factory rear setup would start to go long and soft as heat built. On a 4MATIC saloon that already sits nose-heavy, sharpening rear braking helps the car stay settled and square under hard deceleration rather than diving onto its front axle. The Street, Sport and Racing pad compounds let you match bite and temperature range to how you actually drive – quiet, low-dust and progressive for the commute, with Sport for fast road and Racing for fade-resistant track sessions. Included caliper finishes, from Red through Gold to Anodized Black at no extra cost, mean the look behind the wheel matches the mechanical change.

About the Hollow rear brake kit

The Hollow rear brake kit takes its name from the disc design: a two-piece floating rotor with hollow vanes that trim rotating and unsprung mass without giving up the heat capacity that comes with a larger disc. Less rotating mass at the rear axle means the wheels speed up and slow down with slightly less inertia, which the W204’s chassis reads as crisper response. The kit pairs those discs with an upgraded caliper, hollow-body as standard, that clamps the pad more evenly than the sliding factory unit, spreading load across the friction face and keeping wear consistent; a Hollow Racing upgrade – dust-cover-free, rated to 1000C, with a two-year warranty – is offered for hard track use. Pads come in three compounds – Street, Sport and Racing – covering everything from refined daily stopping to repeated high-temperature braking. Included caliper finishes span Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone for £150, plus premium polished-forged Titanium, Polished Gold and Polished Silver and candy Teal, Blue, Red and Orange. Discs come drilled or slotted at the same price, with two-tone centre bells in five anodized colours or titanium selectable at checkout. It is built as a rear-axle kit, intended to work alongside an equivalent front upgrade for a balanced car.

Fitment for the Mercedes Benz C Class W204 C 300 4matic (2007-2014)

This kit is cut specifically for the W204-generation C-Class in C 300 4MATIC trim, covering the 2007 to 2014 model years. It mounts to the rear axle and is matched to that chassis and drivetrain, so confirm your car is the 4MATIC W204 C 300 rather than a rear-drive or different-engine W204 before ordering. No fitment details are assumed beyond the W204 platform and the model years listed.
