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

The W204 C 300 carries its weight over the front axle, and on a saloon this size the rear brakes spend most of their life as understudies. Push the pace on a quick B-road or a circuit and the rear discs heat-soak long before the fronts have said their piece, which is exactly where the standard setup starts to feel vague underfoot. This XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz C Class W204 C 300 gives the back of the car the thermal headroom it was always short of.

It is a rear-axle upgrade for owners who use the C 300 hard rather than just look at it – the kind who have already sorted the fronts and want the brake balance to match. Supplied as a matched pair of rear calipers and discs, with two-piece floating rotors, a choice of pad compound and a wide range of caliper finishes, it lets you set the rear end up for the way you actually drive.

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

Fit this kit and the most obvious change is consistency: the rear discs shed heat faster, so the pedal stays firm through a sequence of stops instead of going long as the rears cook. The hollow-vane disc design trims rotating and unsprung mass at the rear axle, which the W204 rewards with crisper turn-in and a more settled rear under trail-braking. Choose the Racing compound and you get bite and fade resistance for repeat circuit stops; the Sport compound steps up heat range for fast road and the odd track day; the Street compound keeps things quiet and low-dust for daily use. Because it is a matched rear kit, you also recover proper front-to-rear balance, so the car rotates predictably instead of leaning on the fronts to do all the work.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit takes its name from its disc construction – a two-piece floating rotor with hollow vanes that cut weight while opening up more surface area to airflow for quicker cooling. It is a rear-position kit, designed to pair with an uprated front setup so the whole car stops as a unit. The caliper is hollow-body as standard, with a Hollow Racing upgrade rated to 1000C and a two-year warranty for serious track use. Three pad compounds are offered – Street, Sport and Racing – so the same hardware suits a road-biased C 300 or one that sees regular track time. 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. Everything is sized for the W204 rear axle rather than adapted from a generic fitment, which keeps geometry and clearances correct.
