XYZ Racing Hollow Rear Brake Kit — Mercedes Benz E CLASS W211 E 55 AMG (2003-2009)

The W211 E 55 AMG hides a supercharged 5.4-litre M113K V8 inside a near-1.9-tonne executive saloon, and that mass has to be hauled down again and again. On a rear-drive AMG that squats under power and pitches forward into every braking zone, the rear axle does more thermal work than most owners credit, and the factory rear setup is usually the first thing to go soft once you start using the performance the supercharger gives you.

The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz E Class W211 E 55 AMG (2003-2009) attacks that problem at the back corners. The hollow-vane disc design strips rotating and unsprung mass from the rear, while the upgraded caliper and pad package gives the rear axle the heat capacity to stay consistent through a long fast-road blast or a track session.

What this brake kit does for your 2003-2009 Mercedes Benz E Class W211 E 55 AMG

After fitting, the first thing you notice is a firmer, more progressive rear bite that holds the car steady under hard, repeated stops instead of fading halfway through. The lighter hollow-vane discs cut unsprung weight at the rear, which helps the rear dampers keep the contact patch settled over mid-corner bumps. Pad compound is your call: the Street option keeps things civil for daily driving, the Sport compound adds bite and fade resistance for committed road use and the odd track day, and the Racing compound is there for circuit work where rear stability under trail braking matters most. Because the E 55 loads so much weight onto a hot rear axle, that extra thermal headroom is what keeps the pedal from going long late in a session.

About the Hollow Rear Brake Kit

The kit is built around two-piece floating hollow-vane discs, lightened internally to reduce rotating mass without sacrificing the swept area a heavy AMG saloon needs. It pairs those discs with a performance caliper, hollow-bodied as standard, and a choice of three pad compounds: Street, Sport and Racing, so the same hardware suits a daily-driven E 55 or one that sees regular track time. Serious track users can step up to the optional Hollow Racing caliper, which drops the dust cover, is rated to 1000C and carries a two-year warranty. Calipers come finished in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any Pantone shade and premium polished-forged or candy finishes for matching a particular wheel or paint scheme. Every part is sized specifically for the rear axle of this chassis and supplied as a matched pair rather than adapted from a generic fitment, so the front-to-rear braking balance stays sensible on a car that already works its front brakes hard.
