XYZ Racing Hollow Rear Brake Kit — Mercedes Benz E CLASS S210 E 320 WAGON (φ 12) (1995-2003)

The S210 E 320 Wagon was built to haul. It is a long-roof estate on the W210 platform with a tail that only gets heavier as you load the boot, and a rear axle asked to do more of the braking work than the saloon ever demanded. The XYZ Racing rear brake kit targets exactly that weakness: a bigger, better-cooled rear setup for a 1.6-tonne-plus wagon whose factory rear brakes were specified for a lighter, emptier car, on a pair of two-piece floating discs sized around the φ 12 fitment to match what you are running up front.

Each kit is a pair: left and right rear calipers with matching rear discs, supplied with braided lines for a firmer pedal that does not swell under heat. The discs use a hollow-vane internal structure that drops rotating and unsprung mass while opening up the airflow that carries heat off the friction face, so the rears shed temperature instead of soaking it.

What this brake kit does for your 1995-2003 Mercedes Benz E Class S210 E 320 Wagon

A loaded estate pushes braking demand rearward, and the S210’s rear axle feels it first on long descents and repeated heavy stops. The hollow-vane discs pull heat off the friction face faster, so the rear brakes stay consistent when the boot is full or you are towing instead of fading like a tired factory setup. With the rear pulling its weight, the car stays settled under braking instead of pitching hard onto its nose.

Pad compound is your call. Street is the quiet, low-dust road compound and the sensible default. Sport adds bite and a wider heat range for a firmer pedal under fast-road work. Racing is the full track compound for sustained hard use. The discs can be drilled or slotted at the same price, so the choice is down to looks and feel.

About the Hollow rear brake kit

XYZ Racing builds this as a rear-axle upgrade, not a like-for-like service swap. The discs are two-piece and floating, with a hollow-vane core that removes material where it does nothing for braking, cutting rotating mass and improving airflow over the friction surface. The kit is configured to the φ 12 fitment for this chassis. Centre bell upgrades are on the table too: two-tone anodizing in five colours, or titanium, both selectable when you order.

The caliper is hollow-body as standard. Included painted finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, or specify any Pantone code as a Custom Color for £150. The premium tier covers polished-forged Titanium, Polished Gold and Polished Silver, plus candy finishes in Teal, Blue, Red and Orange. For serious track use there is a Hollow Racing caliper option that drops the dust cover, is rated to 1000C and carries a two-year warranty. It is engineered as the rear partner to a front upgrade, so front-to-rear balance stays sensible rather than over-braking either axle.

Fitment for the Mercedes Benz E Class S210 E 320 Wagon (1995-2003)

This kit is cut for the Mercedes Benz E Class S210 E 320 Wagon built between 1995 and 2003, fitting the rear axle to the φ 12 marker as a matched pair of left and right calipers and discs. It is the estate bodyshell of the W210-generation E-Class in E 320 specification. Confirm your exact build year against the 1995-2003 span before ordering, as the S210 ran through a mid-life facelift within this period.
