Caliper render for this kit:
The 500 E was a private joke between two German manufacturers. Standard W124 body, largely standard interior, but beneath the bonnet Porsche’s engineers had dropped the front subframe by nearly 50mm to accommodate the M119 5.0-litre V8 from the S-Class, then assembled the whole car by hand at Zuffenhausen, shuttling partially built shells between Stuttgart and the 964 production line. The result was 326bhp in a saloon that looked like it should be ferrying someone to a Frankfurt hotel.
The cars built between 1991 and 1993, before production moved back to Sindelfingen for the revised E500, represent the original specification, and they are firmly established classics. Owners keeping them in active use will have found the limits of the factory front brakes: calibrated for the standards of their era, and increasingly reluctant under the repeated, high-speed braking the M119’s torque invites on fast A and B roads. The XYZ Racing front brake kit addresses exactly that deficit with a pair of larger calipers and discs for the leading axle. You set the specification when you order from the options above.
What this brake kit does for your 1991-1993 Mercedes Benz E CLASS W124 500 E
The hollow-vane disc lets heat migrate more efficiently than a conventional vented rotor, which matters particularly on a car carrying the weight of a V8 ahead of the front axle. Fade resistance improves across sustained braking sequences, the kind a 1,700kg saloon with 326bhp generates on a fast descent or a track day. Three pad compounds cover the range of use: Street for quiet, low-dust running on light duties or preservation schedules; Sport for the fast-road driving where this W124 variant earns its reputation; Racing for those taking the car to circuit events.
The lighter two-piece floating disc also trims rotating and unsprung mass at the front corners. Discs are available drilled or slotted at the same price.
About the XYZ Racing Front Brake Kit
The kit uses two-piece floating discs with a hollow-vane profile that increases airflow through the rotor body under hard braking, dispersing heat more aggressively than a standard vented unit and reducing the heat soak that produces pedal fade across repeated high-load stops. Where the factory discs were specified for braking loads typical of 1991 conditions, this kit handles the thermal cycle of a high-mass V8 saloon driven with intent. The caliper is hollow-body forged as standard, fed by braided lines for a firm pedal. Pad selection across Street, Sport and Racing lets the system be configured for actual use rather than a compromise.
Included caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with Custom Color matching any Pantone for 150 pounds. Premium polished-forged finishes cover Titanium, Polished Gold and Polished Silver, and the candy range adds Candy Teal, Candy Blue, Candy Red and Candy Orange. Centre bells can be two-tone in five anodized colours or titanium, and the optional Hollow Racing caliper, rated to 1000C with no dust cover and a two-year warranty, suits serious track use.
Fitment for the Mercedes Benz E CLASS W124 500 E (1991-1993)
This kit is matched to the W124 500 E in the 1991-1993 production window, the original Porsche-assembled generation, distinguished by its modified front subframe geometry from other W124 variants. Confirm your chassis code and front caliper mounting specification before ordering; the 500 E’s unique front-end architecture differs from standard four-cylinder and six-cylinder W124 derivatives sharing the same body.

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 286–380mm (front). 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.
