XYZ Racing Hollow Rear Brake Kit — Bmw 3 SERIES E 91 4WD (OE160) (2006-2012)

The E91 Touring puts more mass over its rear axle than the saloon ever did, and the xDrive driveline adds weight the brakes have to manage on the way into a corner. That combination leaves the standard rear setup working hard once you start braking from speed repeatedly. The XYZ Racing rear brake kit for the BMW 3 Series E91 4WD addresses exactly that, giving the rear axle a pair of discs and a pair of calipers built to shed heat rather than soak it.

This is a rear-specific kit for owners who load the estate, push the car on fast B-roads, or run the odd track day. It is matched to the 2006-2012 E91 4WD and built around two-piece floating discs with a hollow-vane structure that trims rotating mass while keeping thermal capacity high.

What this brake kit does for your 2006-2012 BMW 3 Series E91 4WD

The hollow-vane disc design lowers rotating and unsprung mass at the rear axle, so the suspension settles faster over broken surfaces and the car feels less inert when you trail the brakes into a turn. You get firmer, more linear pedal feel and braking that holds its bite through repeated stops instead of going long and vague. Three pad compounds let you match the kit to use: Street for quiet, low-dust everyday driving, Sport for harder fast-road work, and Racing for sustained circuit sessions. On a heavy 4WD Touring that loads its rear brakes more than most, that consistency is what you notice first.

About the rear brake kit

The two-piece floating discs use a hollow internal vane structure that pulls air through the disc to manage temperature while taking weight off each corner. Lighter discs mean less rotating inertia for the brakes to start and stop, and less unsprung mass for the rear suspension to control, and the floating ring expands on its alloy bell to stay flat under heat. The kit pairs those discs with a fixed caliper and a choice of three pad compounds, Street, Sport and Racing, so the same hardware covers a daily-driven estate or a car seeing regular track use. The caliper body is hollow-cast as standard, with a Hollow Racing upgrade for serious track work. Caliper finishes run from painted Red, Yellow, Gold, Black and Anodized Black at no extra cost through to premium polished-forged, candy and Custom Pantone options, and disc faces are available drilled or slotted with two-tone or titanium centre bells. It is a rear-axle upgrade aimed at bringing genuine thermal headroom to a platform that carries weight where it helps braking least.
