XYZ Racing Hollow Rear Brake Kit — Bmw 3 SERIES E 91 330 (OE185) (2006-2011)

The E91 Touring carries its mass differently to the saloon. Load the boot, add a family or a weekend’s kit, and it is the rear axle that pays for it under braking. On a 330 Touring the standard rear discs were never sized for repeated hard stops from three-figure speeds, and they tell you so with a long, soft pedal by the third or fourth retardation. This XYZ Racing rear brake kit for the Bmw 3 Series E 91 330 (OE185) goes at that problem directly.

It is a rear-axle upgrade, a pair of rear calipers and a pair of two-piece floating discs whose hollow-vane construction trims rotating and unsprung mass while adding the thermal headroom the factory setup runs short of. The payoff is a rear end that holds its bite as the fronts do their work, keeping the car settled instead of letting the back go light under trail braking.

What this brake kit does for your 2006-2011 Bmw 3 Series E 91 330 (OE185)

You feel it first in pedal consistency: the rear stays linear through a sequence of stops rather than going long once heat builds. The lightweight disc design sheds rotating mass, which sharpens turn-in and takes a measure of strain off the rear bearings and dampers. Pad compound is your call: Street for quiet, low-dust road use, Sport for fast B-road and occasional track days, Racing for sustained circuit work where fade resistance matters most. A full range of caliper finishes, including painted Red, Yellow, Gold, Black and Anodized Black at no extra cost, lets the hardware suit the car rather than shout over it.

About the rear brake kit

The kit replaces the rear discs and calipers as a matched assembly. The two-piece floating disc is the point of it: removing material from the hollow-vane disc body lowers rotational inertia and unsprung weight without surrendering swept area, so the brake works the rear tyre harder while asking less of the suspension. The floating ring expands on its alloy bell, staying flat under heat where a fixed solid rotor would distort. The disc and caliper are sized to the rear axle’s actual job rather than copying front-kit numbers, which keeps brake balance sensible on a rear-drive or xDrive 330. Three pad compounds span quiet daily commuting (Street) through fast road (Sport) to repeat-lap circuit sessions (Racing). Caliper colour spans painted Red, Yellow, Gold, Black and Anodized Black at no cost, with premium polished-forged, candy and Custom Pantone options, and disc faces come drilled or slotted with two-tone or titanium centre-bell upgrades. The caliper is hollow-cast as standard, with an optional Hollow Racing version for serious track use.
