Caliper render for this kit:

The W215-generation CL 600 was built to cover long distances at high speed in near silence, and that brief made it heavy. A V12 grand tourer of this mass loads its rear axle hard every time it scrubs off motorway pace, and the factory rear discs were chosen for refinement and service life rather than for repeated, committed stops. This XYZ Racing Rear Big Brake Kit for the Mercedes Benz CL 600 W215 (2000-2006) tackles that directly, adding thermal headroom and bite to an axle that earns its keep on a car this size.
Because it is a rear-specific kit, it is as much about balance as outright stopping power. On a nose-heavy coupe carrying the better part of two tonnes, a rear axle that keeps biting helps the W215 settle into a corner and stops the front brakes from shouldering the entire workload. Match the pad compound to how you actually use the car and the upgrade does the rest.
What this big brake kit does for your 2000-2006 Mercedes Benz CL 600 W215
The change you feel first on a heavy W215 is consistency. The two-piece floating disc carries more thermal mass and feeds air through its vanes, so brake temperature climbs more slowly on a fast B-road or a long Alpine descent and the pedal stays where you left it instead of going long. Three pad compounds let you set the car up properly: Street for quiet daily use, Sport for keener bite when you press on, and Racing for sustained heat without the fade a standard CL 600 will show after a few hard stops in succession. A rear axle that holds its bite also takes load off the front discs, which is exactly what a front-biased grand tourer of this weight needs. The result is a firmer, more reassuring pedal and a back end that feels planted rather than reluctant.
About the Rear Big Brake Kit
This is a bolt-on rear brake upgrade engineered around the W215 platform. It pairs a hollow-body forged caliper, the standard caliper construction here, with a larger two-piece floating disc and your choice of pad friction material, raising the heat capacity and clamping consistency of the rear axle over the original setup. The disc’s friction ring floats on an alloy bell so it can grow with heat without warping. Painted calipers 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 available, so the hardware reads cleanly behind an open rear wheel. The pad range spans Street, Sport and Racing compounds, letting you tune rear bite and high-temperature behaviour to your driving without changing the rest of the kit. Built for a car that mixes everyday refinement with genuine pace, it adds capability at the rear without turning a comfortable coupe into something harsh.
Fitment for the Mercedes Benz CL 600 W215 (2000-2006)
This kit is specified for the W215 CL 600 across the 2000 to 2006 model years, fitting the rear axle. Confirm your chassis code is W215 and your build year falls within that span before you order, and select your caliper colour, disc style and pad compound to complete the spec.

Choosing your spec
Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.
Brake pads — Street, Sport or Racing
Every kit ships with a full set of high-performance pads; the compound is your call.
Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.
Caliper grade — Hollow vs Hollow Racing
Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.
Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 330–356mm (rear). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.

Caliper colour & finish
Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).
Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.
Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).


Centre bells
The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
