XYZ Racing Hollow Rear Brake Kit — Mercedes Benz C CLASS W204 C 320 4MATIC (2007-2014)

The W204 C-Class was built as a refined compact saloon first, and its standard rear brakes reflect that brief – fine for motorway work, less convincing once you start leaning on them. Add the 4MATIC driveline’s extra mass through the axles and the C 320 asks more of its rear corners than the lighter rear-drive cars in the range. The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz C Class W204 C 320 4matic (2007-2014) is aimed squarely at that gap.

Supplied as a matched pair of rear calipers and discs, the two-piece floating rotors shed rotational weight while opening up cooling area, so the rear axle recovers between stops instead of heat-soaking. With Street, Sport and Racing pad compounds on offer, you set the kit up for the way you actually drive the car – daily commute, quick B-road, or repeated hard stops on a circuit.

What this brake kit does for your 2007-2014 Mercedes Benz C Class W204 C 320 4matic

On the road you feel it first as bite: a firmer, more progressive pedal that needs less travel to load the rear axle. The hollow-vane discs carry less rotational and unsprung weight, which sharpens how quickly the rear responds and takes a little strain off the dampers over broken surfaces. Under harder use the freer airflow keeps pad and fluid temperatures in check, so the pedal stays consistent when the factory setup would start going long and soft. Pick the Racing compound for the friction and fade resistance circuit work demands, Sport for fast road and the odd track day, or the Street compound to keep things quiet and clean-wheeled for everyday driving. It is a rear-axle change that makes the whole car feel more planted when you stand on the brakes.

About the Hollow Rear Brake Kit

XYZ Racing builds this kit around two-piece floating discs whose hollow vanes remove material from the disc body to cut rotating mass without surrendering swept area. Less weight at the wheel means faster heat shedding and quicker response, and the design also helps vent the heat that repeated braking dumps into the rear axle. The caliper is hollow-body as standard, with a Hollow Racing upgrade – no dust cover, rated to 1000C, with a two-year warranty – for cars run hard on circuit. The kit is engineered specifically for the rear of the car, so it complements the existing front balance rather than overwhelming it. Three pad compounds cover the spread of use: Street for a stock-feel road car, Sport for a sharper everyday bite and wider heat range, and Racing for sustained high-temperature track sessions. Included caliper finishes are 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.
