Caliper render for this kit:

The W210 E 320 was built to waft: a torquey 3.2-litre six in a soft, comfort-sprung executive saloon that hides its mass well right up until you lean hard on the brakes and feel the nose drop. The XYZ Racing Hollow Rear Brake Kit attacks the back axle of that equation, adding thermal headroom and a firmer, more consistent rear bite to a 1995-2003 Mercedes Benz E-Class that spends its life carrying real weight.
This is the rear half of a big brake upgrade, sized for a car that loads its dampers under hard stops and asks too much of standard discs on a long descent or a quick B-road. With three pad compounds and a hollow-vane disc design that trims rotating mass, it is aimed at owners keeping a W210 sharp rather than standard.
What this big brake kit does for your 1995-2003 Mercedes Benz E-Class W210 E 320
On a heavy rear-drive saloon, rear brake performance sets how settled the car stays when you trail the pedal into a corner. Fit this kit and the W210 holds pedal feel through repeated hard applications, where the factory rears would start to go long and vague. The hollow-vane discs shed a little rotating and unsprung mass at each rear corner, which the W210’s multi-link rear axle rewards with crisper recovery over mid-corner bumps. Run the Street compound for quiet daily road manners, the Sport compound for harder fast-road work and the odd track day, or the Racing compound when sustained heat is the enemy. Included caliper colours span Red, Yellow, Gold, Black and Anodized Black, so the hardware reads as deliberate behind the wheels.
About the Hollow Rear Brake Kit
The XYZ Racing Hollow Rear Brake Kit is the rear-axle half of a big brake conversion built around a fixed caliper and a two-piece floating disc whose hollow vane construction removes material where it does no braking work. That is the point of the "hollow" name: lower rotating mass, so the rear axle spins up and slows with less inertia, without surrendering swept area. Three pad compounds let you match friction to use: Street for commuting, Sport for spirited road driving, and Racing for high-temperature track or hill work. 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. Calipers come in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any Pantone shade and premium polished-forged or candy finishes available, and the kit is supplied as a matched disc, caliper and pad pair for the E 320 rather than a parts-bin assembly. As a rear-only kit it is designed to partner an upgraded front or to rebalance a car already running bigger front brakes.
Fitment for the Mercedes Benz E-Class W210 E 320 (1995-2003)
This kit is mapped to the W210 E-Class in E 320 specification across the 1995-2003 production run, fits the rear axle only and is supplied as a pair of rear calipers and discs. Confirm your car is the W210 chassis in E 320 trim before ordering, as the platform spans several engine and brake specifications over those years.

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.
