XYZ Racing Hollow Rear Brake Kit — Mercedes Benz S CLASS W220 S 350 (2002-2005)

The W220 S 350 hides its mass well, but the better part of two tonnes of long-wheelbase saloon still has to be hauled down every time you lift off a motorway cruise, and on a car this size the rear axle does more braking work than owners expect. The standard discs were specified for a comfort-first luxury barge, not for repeated hard stops with four adults and a full boot aboard, and they show it when heat builds. This XYZ Racing rear big brake kit for the Mercedes Benz S Class W220 S 350 replaces that setup with a larger, better-cooled rear corner.

Built around XYZ Racing’s two-piece floating disc and supplied as a matched pair of rear calipers and rear discs, the kit trims rotor weight at the hub while adding swept area, so the rear of the W220 stays composed under the kind of stopping the original brakes only tolerated in short bursts. It is a refresh aimed at owners keeping these big-engined Mercedes saloons sharp rather than just serviceable.

What this brake kit does for your 2002-2005 Mercedes Benz S Class W220 S 350

On a heavy rear-drive saloon, rear brake fade arrives as a soft, lengthening pedal and a tail that squats and shuffles under load. The added disc diameter and the two-piece floating disc here give the rear axle more thermal headroom, so pedal feel holds firm through successive stops instead of going long. Reduced rotor mass also takes weight off the unsprung corner, which helps the Airmatic-equipped rear settle more quickly over broken surfaces. With three pad compounds offered, Street, Sport and Racing, you can match the rear bite to how the car is actually used, from refined, low-dust daily mileage, through fast-road work with a wider heat range, to harder driving. The result is a W220 that stops straighter, sits flatter under braking, and feels its weight far less.

About the rear big brake kit

The kit is built around XYZ Racing’s two-piece floating disc, which removes material from the rotor to cut rotating and unsprung mass without surrendering swept area or strength; the ring is offered drilled or slotted at the same price. Larger discs and uprated calipers replace the factory rear hardware to raise thermal capacity, the single biggest weakness of the original setup on a saloon this heavy. The caliper is hollow-bodied as standard, with a Hollow Racing upgrade (no dust cover, rated to 1000C, two-year warranty) for hard track use. Three pad compounds are available, Street for refined, low-dust road use, Sport for harder fast-road driving with a wider heat range, and Racing for the most demanding work, so the kit can be specified to the owner’s intent rather than sold as a one-size component. Painted caliper finishes come at no cost in Red, Yellow, Gold, Black or Anodized Black; a Custom Color in any Pantone is GBP 150, and premium polished-forged finishes (Titanium, Polished Gold, Polished Silver), candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) and two-tone or titanium centre bells are also available, visible through the W220’s larger wheels. It is engineered as a direct rear upgrade for the S 350, pairing meaningful performance gain with a finished, OE-grade appearance.
