XYZ Racing Hollow Rear Brake Kit — Bmw 3 SERIES E 91 320 (OE185) (2006-2011)

The E91 Touring carries more weight over its rear axle than the saloon it shares a platform with, and that extra mass tells under hard braking, especially with a loaded boot on the way to a track day. The XYZ Racing rear brake kit for the Bmw 3 Series E 91 320 (OE185) tackles the back end of that equation, replacing the modest rear setup that the 320i and 320d inherited largely unchanged from the lesser cars in the range.

This is a rear-axle upgrade: a pair of rear calipers and a pair of two-piece floating discs, sized to trim rotating and unsprung mass where the standard E90-series rear brakes tend to run hot. With three pad compounds and a full range of caliper finishes to choose from, it lets you match rear bite to how you actually use the car, from committed fast-road driving to repeated heavy stops on circuit.

What this brake kit does for your 2006-2011 Bmw 3 Series E 91 320 (OE185)

Most owners chasing better stopping power look to the front first, but on an E91 the rear is where balance under trail braking is won or lost. Adding bite at the back settles the car as you load the nose into a corner, so the tail stays planted rather than going light over a crest or a kerb. The lightweight disc sheds rotating mass, which sharpens initial response and helps the rear cope with the heat that builds during back-to-back stops. The Racing compound holds its feel after several hard laps, Sport bridges fast road and the odd track day, while the Street pad keeps cold bite and lower dust for daily use. The upshot is a rear axle that finally matches the confidence you want from the front of the car.

About the rear brake kit

This is XYZ Racing’s rear-axle package for the E90/E91 platform, designed to lift the 320’s understated factory rear brakes to something that suits harder driving. The two-piece floating discs use a hollow-vane structure that strips rotating and unsprung mass without giving up swept area, so the rear comes up to temperature quickly and sheds it just as readily. The floating ring runs on the alloy bell, staying flat under heat where a fixed solid rotor would distort. Three pad compounds are offered: Street for a quiet, low-dust road default, Sport for stronger bite and heat range, and Racing for circuit duty. The caliper is hollow-cast for stiffness, with an optional Hollow Racing version (no dust cover, 1000C rating, two-year warranty) for serious track use. Painted caliper colours include Red, Yellow, Gold, Black and Anodized Black at no extra cost, with premium polished-forged and candy finishes alongside a Custom Pantone option.
