XYZ Racing Hollow Rear Brake Kit — Mercedes Benz S CLASS W220 S 320 (1998-2002)

The W220 S-Class hides its mass well right up until you ask the brakes to repeat the favour. On the S 320, a comfort-tuned saloon built to cross continents at a cruise, the rear axle does quiet but constant work hauling close to two tonnes down from motorway pace. This XYZ Racing Rear Big Brake Kit for the Mercedes Benz S Class W220 S 320 (1998-2002) replaces the standard rear setup with a lighter, more thermally stable package that holds its bite when the original discs would start to glaze and go long.

Supplied as a matched pair of rear calipers and rear discs, the two-piece floating disc trims rotating mass at the back axle, while the larger friction area gives the rear of the car more to lean on during sustained or repeated stops. For a heavy executive saloon that spends its life loaded with passengers and luggage, that rear-axle reserve is exactly where the factory brakes begin to feel vague.

What this brake kit does for your 1998-2002 Mercedes Benz S Class W220 S 320

Fitted to the rear of the W220, this kit firms up pedal response and pushes back the point where the brakes start to fade under heavy or back-to-back stops. The two-piece floating disc sheds heat faster than the solid factory item, so a car carrying four adults and a boot full of luggage settles into a more consistent pedal. You also get to match the friction to how you drive: the Street compound suits everyday motorway miles with low dust, Sport steps up the bite and widens the heat range, and the Racing compound is there for owners running their S 320 hard on faster roads. The end result is a rear axle that contributes more honestly to overall stopping balance rather than trailing the fronts.

About the rear big brake kit

The kit is built around a vented two-piece floating disc that cuts rotating weight without giving up swept area, paired with XYZ Racing calipers clamped onto the rear hubs of the W220; the ring can be specified drilled or slotted at the same price. The floating profile aids cooling and helps the disc shrug off the heat soak that comes from braking a heavy saloon repeatedly. 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 offered: Street for refined, low-dust daily use, Sport for sharper response and a wider heat range on a fast road, and Racing for the most committed driving. 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, so the upgrade can sit discreetly behind the wheels or stand out against them. It is a bolt-on brake package designed specifically for this chassis rather than a generic disc swap.
