XYZ Racing Hollow Rear Brake Kit — Mercedes Benz CLS 350 C219 (2004-2010)

The C219 CLS 350 hides its mass well until you ask it to stop. At a kerb weight comfortably over 1.7 tonnes, this M272-powered four-door coupé loads its rear axle hard under braking, and the factory rear discs were sized for refined cruising rather than repeated heavy stops. The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz CLS 350 C219 targets the rear end specifically, where heat soak and fade tend to show up first on a quick B-road or a track day.

This is a rear-axle upgrade built around two-piece floating discs that shed rotating mass while adding thermal headroom. Paired with your choice of pad compound, it gives the CLS the rear braking stability the chassis asks for when the front end is already working hard into a corner.

What this brake kit does for your 2004-2010 Mercedes Benz CLS 350 C219

On the road you will feel a firmer, more linear pedal and a rear axle that settles rather than squirms when you brake into a bend. The two-piece floating disc trims rotating mass, which helps the rear wheels follow the surface and eases the work asked of the CLS’s traction and stability electronics. Pick the Street compound for everyday driving, the Sport compound for sharper bite with strong cold response and the odd track day, or the Racing compound if you run track days and need the rear to hold up under repeated heavy stops. Because this kit works the rear axle, it restores brake balance on a car that, like most fast Mercedes saloons, leans heavily on its front discs from the factory.

About the XYZ Racing Hollow Rear Brake Kit

The kit is built around a two-piece floating disc whose friction ring rides on an alloy bell, the rotor cast to remove material from its internal structure and cut rotating and unsprung mass without giving up the swept area you need for heat management. Less rotating mass lets the rear brakes slow the wheel more readily, which sharpens response and reduces the gyroscopic effect that blunts steering and ride quality. The caliper is a hollow-body forged unit as standard, offered in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any Pantone for a small upcharge and premium polished-forged or candy finishes, so it can sit discreetly behind the wheel or make a statement through the spokes. Pad compound is specified separately, with Street, Sport and Racing options spanning daily commuting through to circuit use. The package is engineered as a direct-fit rear brake kit for the CLS 350, so mounting and geometry are matched to the C219 rather than adapted from a generic template.
