Fits Bmw 3 SERIES E 91 323 (OE160) (2006-2011)

Brake pad compound

Street: quiet, low-dust, strong cold bite for road driving. Sport: higher temperature range and more bite for fast road and occasional track. Racing: maximum fade resistance for sustained track use (noisier and dustier cold). Match the pad to how hard you actually brake.

Disc size

Caliper grade

Hollow is the standard caliper: a lighter hollow-body forged caliper with a dust cover and a 5-year warranty. Hollow Racing drops the dust cover for sustained high-temperature use (rated to 1000°C, 2-year warranty) — the track-grade choice.

Caliper colour

Painted colours are included. Polished-forged finishes are mirror-polished forged calipers (Titanium, Gold, Silver); candy colours are a deep, mirror-reflection paint. Both are premium upgrades — fuller detail further down the page.

Painted — includedTell us the exact Pantone (PMS) code you want the calipers painted.Polished forgedCandy
Disc style

Drilled discs (cross-drilled holes) vent gas and water and look aggressive; slotted discs (surface grooves) wipe the pad face clean and resist fade under sustained hard use. Same price — choose on looks or how you drive.

Centre bell

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. Standard anodized is included; a two-tone bell adds an anodized accent ring in your choice of colour; titanium is the lightest, forged option.

Carbon-ceramic rotor

Carbon-ceramic rotors are a special-order track upgrade: far lighter than steel, fade-resistant at extreme temperatures and extremely long-lived. The price follows the disc size you choose above. The standard two-piece steel rotor is included.

XYZ Racing Hollow Rear Brake Kit — Bmw 3 SERIES E 91 323 (OE160) (2006-2011) — 330 mm
330 mm

The E91 Touring carries its mass differently to the saloon: the longer tail, the load floor and whatever sits behind the rear seats all hang over the back axle, and that rearward weight leans hard on the rear brakes through repeated stops. The 323’s straight-six is no monster on paper, but a fast-road or track-day E91 still loads its rear discs well past what the standard setup was specified to shrug off.

This XYZ Racing rear brake kit, in the OE160 rear fitment, answers that with a pair of two-piece floating rear discs, a pair of uprated rear calipers, and a choice of pad compound to match how hard you actually drive. It is a rear-axle upgrade for owners who want stronger, more consistent retardation without changing the car’s road manners.

What this brake kit does for your 2006-2011 Bmw 3 Series E 91 323 (OE160)

The hollow-vane disc design strips rotating and unsprung mass from each rear corner, which the steering and rear multi-link can feel as cleaner turn-in and better composure over bumps. More usable thermal capacity at the back means the pedal stays firm through a sequence of hard stops rather than going long as standard discs heat-soak. With three pad compounds you set bite and fade resistance to suit: Street for everyday quiet, low-dust road use, Sport for harder fast-road work with the occasional track day, and Racing for sustained circuit sessions. The net effect is more braking confidence at the rear axle and a more balanced car under trail braking.

About the rear brake kit

The kit is built around two-piece floating rear discs that cut weight where it counts most, at the rotating, unsprung corner, while keeping the swept area needed to manage heat under repeated load. The floating ring works against the alloy bell to stay flat as it expands, resisting the warping a fixed solid rotor suffers when worked hard. Three pad compounds are offered: Street for road use, Sport for harder fast-road driving, and Racing for sustained circuit work, so one set of hardware spans daily duty to track sessions. Caliper finish is yours to set, with painted Red, Yellow, Gold, Black and Anodized Black at no extra cost, plus premium polished-forged and candy options and a Custom Pantone route. The caliper body is hollow-cast as standard, with an optional Hollow Racing upgrade for serious track use. As a rear-specific OE160 kit, it targets the back axle of the E9x Touring rather than reusing a generic one-size casting.

Choosing your spec

Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.

Brake pads — Street, Sport or Racing

Every kit ships with a full set of high-performance pads; the compound is your call.

Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.

Caliper grade — Hollow vs Hollow Racing

Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.

Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 330–356mm (rear). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.

Caliper colour & finish

Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).

Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.

Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).

Centre bells

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
