XYZ Racing Hollow Rear Brake Kit — Mercedes Benz E CLASS W124 500 E (1991-1993)

The W124 500 E carries its V8 and near-1.7-tonne kerb weight in a way few period saloons did, and all of that mass loads the rear axle every time you brake hard from speed. This XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz E CLASS W124 500 E (1991-1993) goes straight at that rear-axle workload, replacing the factory setup with a stiffer, lighter, better-cooled package.

For a Porsche-assembled Q-car that owners now run as a fast, usable modern classic, the rear of the braking system matters more than most people expect. Specify it alongside a front kit and the 500 E sheds speed with the composure the chassis always deserved.

What this big brake kit does for your 1991-1993 Mercedes Benz E CLASS W124 500 E

Fit this kit and the first thing you feel on the 500 E is a firmer, more progressive pedal when you lean on it. The hollow-vane two-piece disc trims rotating and unsprung mass at the rear, which sharpens how quickly the axle reacts and eases the job of the self-levelling rear suspension. Three pad compounds, Street, Sport and Racing, let you set the rear bite to match how you actually drive, from motorway miles through committed back-road work to circuit use. On a heavy V8 saloon, getting front and rear braking into balance is what stops the nose diving and keeps the car from running wide into a corner. The result is a 500 E that pulls up straighter and stays planted under repeat stops.

About the Hollow rear brake kit

XYZ Racing’s Hollow rear brake kit takes its name from a weight-saving disc construction that removes material where it adds mass rather than strength, cutting the weight spinning at each rear wheel on a two-piece floating rotor. Less rotating mass means heat builds and clears more evenly, so braking stays consistent instead of going soft when worked. The kit is offered with three pad compounds: a Street pad for quiet, low-dust everyday use, a Sport compound for harder road driving and the odd track day, and a Racing compound for sustained high-temperature work. The caliper is a hollow-body design 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. Included caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone shade available for an upcharge and premium polished-forged or candy finishes on offer too, so the hardware can sit discreetly behind the wheels or read as part of the build. Every part is specified for the rear axle of the 500 E rather than adapted from a generic fitment.
