Caliper render for this kit:
The W124 300 CE’s long M103 or M104 inline-six sits well ahead of the front axle, concentrating the car’s weight over the leading wheels every time it slows from speed. The original Mercedes front braking hardware was specified for composed autobahn touring, not the repeated hard stops these coupes increasingly see at classic track days and fast-road events three and a half decades on. The XYZ Racing front brake kit replaces that leading-axle setup with a pair of larger calipers and discs that account for how the 300 CE is actually being driven now.
These coupes are no longer just display pieces. Owners who run them hard know the W124’s rear-wheel-drive balance and the 300 CE’s coupe shell reward enthusiastic driving, and the braking should match that ambition. You set compound and caliper colour when you order from the options above.
What this brake kit does for your 1987-1992 Mercedes Benz E CLASS W124 300 CE
The two-piece floating disc reduces rotating and unsprung mass compared with the W124’s original front disc, improving initial pedal response and limiting fade through the repeated trail-braking that loads the front axle hard. The hollow-vane construction vents air through the rotor body to draw heat away during sustained stops. Three pad compounds serve very different operating temperatures: Street for quiet, low-dust daily use, Sport for spirited fast-road driving, and Racing for sustained circuit and hillclimb work.
Discs are available drilled or slotted at the same price, and the caliper colour finishes let you build to a careful restoration or a more assertively presented track machine.
About the XYZ Racing Front Brake Kit
The kit uses two-piece floating discs with hollow-vane construction that improves heat dissipation over the original W124 front disc, reducing thermal build-up through sustained hard use. It is a front-axle fitment, compatible with the 300 CE’s existing rear brake setup, where front and rear bias matter to the car’s balance. The caliper is hollow-body forged as standard, fed by braided lines for a firm pedal. Pad compounds, Street, Sport and Racing, cover the range from quiet preserved-feel road use through to aggressive, high-temperature circuit performance.
Included caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, making it straightforward to match the W124 300 CE’s classic coupe body. Custom Color matches any Pantone for 150 pounds, which covers period-correct colour matching for restorations and personalised builds. 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.

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.
