Fits Bmw 3 SERIES E 91 320 (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 91 320 (OE160) (2006-2011) — 330 mm
330 mm

The E91 is the Touring body of BMW’s E90-generation 3 Series, and the extra mass it carries over the rear axle, boot loaded or not, is exactly why the back end of a 320 deserves more than its standard discs. The XYZ Racing rear brake kit gives the 2006-2011 320 Touring a larger, lighter rear setup that keeps braking balance honest once you start using the car hard.

This is a rear-axle upgrade: a pair of rear calipers and a pair of two-piece floating discs for the back of the car. The discs use a hollow-vane design that strips rotational and unsprung mass without giving up swept area. On a rear-driven estate that already sits its weight further back than the saloon, that matters. You get a sharper, more progressive rear, and a car that stays settled rather than nervous as you trail the brakes into a corner.

What this brake kit does for your 2006-2011 Bmw 3 Series E 91 320 (OE160)

Fit the kit and the first thing you feel is how much more linear the rear axle becomes under load. The discs reduce rotating mass, so the brakes shed heat faster and recover quicker between stops. That tells on a long downhill B-road or a run of roundabouts where the standard rear setup starts to go soft. Pad compound is your call: Street is the quiet, low-dust road default, Sport steps up bite and heat range for fast road and the occasional track day, and Racing is the track compound for when the 320 sees circuit time. Lighter discs also mean less mass for the rear suspension to control, which shows up as cleaner behaviour over mid-corner bumps.

About the rear brake kit

Removing material from the disc’s internal vane structure cuts weight from the rotating assembly while keeping the friction surface intact, lowering the gyroscopic and unsprung load each rear corner has to manage. Lighter discs spin up and slow down with less inertia, so response is quicker and heat builds more slowly. The two-piece floating disc lets the friction ring expand and contract independently of the alloy bell, which keeps the disc flat and resists warping under repeated heavy use. The caliper body is hollow-cast as standard for stiffness without bulk; serious track users can specify the optional Hollow Racing caliper, which drops the dust cover, is rated to 1000C and carries a two-year warranty. Disc faces come drilled or slotted at the same price, and the centre bell can be upgraded to a two-tone anodized finish in five colours or to titanium.

Fitment for the Bmw 3 Series E 91 320 (OE160) (2006-2011)

This kit is specified for the E91 320 Touring built between 2006 and 2011, referenced against the OE160 disc fitment. It is a rear-axle kit, so it sits behind your existing or upgraded front brakes. Confirm your exact build year and the OE160 reference against your car to be certain of a direct fit.

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.
