XYZ Racing Hollow Rear Brake Kit — Mercedes Benz S CLASS W220 S 430 (1998-2005)

The W220 S 430 is the wrong end of two tonnes, and most of that mass sits over the front axle of the M113 4.3 V8. That weight bias is exactly why the rear brakes on these cars get overlooked and then quietly cooked on a long downhill run or a brisk B-road. This XYZ Racing Rear Big Brake Kit for the Mercedes Benz S Class W220 S 430 addresses the rear axle directly, giving a heavy luxury saloon the thermal headroom its standard rear setup was never really specified for.

It is a rear-position kit, supplied as a matched pair of rear calipers and rear discs and built around lightweight two-piece floating discs, so you add stopping capacity without piling on unsprung mass at a corner that the Airmatic-equipped W220 is already asking a lot of. For owners keeping a V8 S-Class properly sorted in 2026, this is the part that restores confidence to the back axle.

What this brake kit does for your 1998-2005 Mercedes Benz S Class W220 S 430

On a car this heavy, fade is the enemy long before outright bite is. The two-piece floating disc trims rotational and unsprung weight at the rear, which the W220’s ride and steering feel will both thank you for. Three pad compound options, Street, Sport and Racing, let you match the rear axle to how the car actually gets used, from a refined, low-dust daily cruiser, through fast-road work with a wider heat range, to a hard-driven keeper that sees the occasional spirited run. The practical result is a firmer, more progressive pedal, better resistance to heat soak on repeated stops, and a rear end that stays composed when you load it up while keeping front-and-rear balance honest. Braking a two-tonne saloon is as much about consistency as it is about peak force, and that consistency is what this kit is built to hold.

About the rear big brake kit

The kit uses lightweight two-piece floating discs that strip mass from the rear corners while keeping the structural strength needed to haul down a large saloon; the ring is offered drilled or slotted at the same price. It is offered with three pad compounds, Street, Sport and Racing, so the kit can be specified soft enough for quiet daily use or aggressive enough for harder driving. 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, and comes in no-cost painted finishes, Red, Yellow, Gold, Black or Anodized Black, with a Custom Color in any Pantone for GBP 150 more. 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 round out the options. The design priority is rear-axle thermal stability and a cleaner, more linear pedal, rather than chasing a single headline number. For a W220 owner, that means a rear brake package matched to the realities of the chassis: heavy, refined, and unforgiving of brakes that fade.
