Caliper render for this kit:

The W211 E 63 AMG hides a violent streak under its executive bodywork: a naturally aspirated 6.2-litre M156 V8 making north of 500 bhp, strapped to a saloon that tips the scales near 1.8 tonnes and is electronically held to 155 mph. All of that mass has to be hauled back down, and on a rear-driven AMG the back axle carries more of that load than most owners credit, particularly once you start using the M156 the way it asks to be used.
That is the gap this XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz E Class W211 E 63 AMG is built to close. It adds disc area and caliper clamping at the rear, where the standard AMG setup runs short of thermal headroom on repeated hard stops, so the car still feels planted from three-figure speeds rather than soft and long.
What this big brake kit does for your 2003-2009 Mercedes Benz E Class W211 E 63 AMG
The first thing you notice after fitment is a firmer, more repeatable pedal. A larger rear disc shrugs off the heat that builds when a heavy saloon is braked hard back to back, which keeps bite consistent instead of trailing away as the fade sets in. Upgraded rear clamping also helps the W211 settle under braking, steadying the back end as weight transfers forward on turn-in. Three pad compounds, Street, Sport and Racing, let you match the rear axle’s character to how the E 63 actually gets driven, from refined road miles through fast-road work to sustained track stops. The result is more braking confidence from a car that has always had far more engine than its factory anchors were comfortable with.
About the Hollow Rear Brake Kit
The Hollow Rear Brake Kit is XYZ Racing’s bolt-on rear braking upgrade, pairing a larger two-piece floating hollow-vane disc with an uprated caliper to lift heat capacity and clamping force over the standard E 63 hardware. The caliper is hollow-bodied as standard, with an optional Hollow Racing upgrade for serious track use that drops the dust cover, is rated to 1000C and carries a two-year warranty. Pad material is specified when you order, in Street, Sport or Racing compound, so the kit can be set up for road use, mixed fast-road and circuit work, or harder track sessions. Caliper finishes cover the included Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone shade and premium polished-forged or candy finishes available, letting the kit sit discreetly behind the wheels or read clearly as an AMG that has been seriously upgraded. It is a focused rear-axle package supplied as a matched pair, a sensible partner to a matched front upgrade, or a fix for owners who already feel the back of the car running out of stopping power first.

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.
