XYZ Racing Hollow Rear Brake Kit — Mercedes Benz CLS C218 (2011-2018)

The C218 CLS carries close to 1.8 tonnes of four-door coupé over a long wheelbase, and that mass lands hard on the rear axle every time you wash off speed from a motorway cruise or a quick B-road run. This XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz CLS C218 (2011-2018) swaps the standard rear setup for a larger, better-ventilated package built to shed heat rather than soak it up.

Rear brakes on a fast GT do quieter work than the fronts, but on a CLS they manage stability under hard stops and keep the back axle settled when you trail the pedal into a corner. The two-piece floating disc strips rotating and unsprung mass from the rear, sharpening response without unsettling the car’s long-legged, composed character.

What this brake kit does for your 2011-2018 Mercedes Benz CLS C218

After fitment you feel the rear axle hold its bite through repeated stops, instead of the pedal going long and wooden as the standard discs heat-soak. The lighter two-piece floating disc cuts unsprung weight at the rear, which helps the dampers keep the tyres planted over broken surfaces. Three pad compounds, Street, Sport and Racing, let you match rear bite to how you actually use the car, from settled daily driving to harder fast-road and track work. Run alongside a matching front upgrade, the kit restores front-to-rear balance so the CLS stops square rather than diving onto its nose.

About the Hollow Rear Brake Kit

The kit is built around a two-piece floating disc whose friction ring rides on an alloy bell, removing material from the rotor’s internal structure to drop weight while keeping the friction face and vane geometry intact for cooling and letting the ring grow with heat without warping. It is a rear-specific package sized to suit the C218’s rear hubs, paired with a hollow-body forged caliper as standard. You spec one of three pad compounds, Street for road use, Sport for harder mixed driving and occasional track, and Racing for track sessions, so the rear end can be set up with the same intent as the front. Painted caliper finishes come 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 the kit can sit discreetly behind the wheels or read as a visible part of the build. The whole design is aimed at managing the thermal load a heavy GT puts through its rear axle under repeated hard braking.
