Fits Bmw 3 SERIES E 92 323 (OE160) (2007-2011)

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 92 323 (OE160) (2007-2011) — 330 mm
330 mm

On a rear-wheel-drive E92, the rear axle does more braking work than most owners credit. It settles the car on turn-in and keeps the tail planted when you trail the pedal into a corner. The XYZ Racing rear brake kit for the BMW 3 Series E92 323 (OE160) swaps the standard rear setup for a pair of larger, lighter two-piece floating discs and a pair of fixed calipers, restoring rear bite that the factory single-piston sliding caliper bleeds away once it gets hot.

This is a rear big brake kit built for balance rather than headline numbers. The 323’s N52 straight-six never asked for monster stopping power, but the chassis carries far more cornering speed than its OE rear brakes were specced to manage on a back road or a track day. Paired with a front upgrade, this kit re-establishes the front-to-rear bias the multi-link rear axle wants under hard, repeated use.

What this brake kit does for your 2007-2011 BMW 3 Series E 92 323 (OE160)

The fixed caliper removes the flex and taper-wear of the original sliding design, so the pedal stays firm and predictable deep into a braking zone. The hollow-vane rotor construction strips rotating and unsprung mass from the rear of the car, which lets the E92’s rear suspension settle quicker over mid-corner bumps and sharpens how the coupe rotates on the brakes. Three pad compounds, Street, Sport and Racing, let you match the rear axle to how you actually drive, from quiet low-dust commuting through fast road to sustained track sessions where the OE setup would start fading. The larger swept area also holds temperature more evenly across the disc face, keeping rear braking torque consistent when the pace climbs.

About the rear brake kit

The kit centres on a big-brake two-piece floating rotor with a hollow-vane, lightweight construction that cuts mass without giving up thermal capacity. The floating ring expands on its alloy bell and stays flat under heat, resisting warping that fixed solid rotors suffer when worked hard. The fixed caliper clamps a larger disc than the factory rear unit, increasing both pad contact area and the leverage the rear brakes can apply, and it is hollow-cast as standard with a Hollow Racing upgrade for serious track use. Pad selection spans a quiet Street compound, a higher-bite Sport compound, and a Racing compound for circuit work, so the kit suits a daily 323 as readily as a weekend track car. Caliper finishes include painted Red, Yellow, Gold, Black and Anodized Black at no extra cost, with premium polished-forged, candy and Custom Pantone options, and disc faces are available drilled or slotted with two-tone or titanium centre bells.

Fitment for the BMW 3 Series E 92 323 (OE160) (2007-2011)

This kit is matched to the BMW 3 Series E92 323 coupe in the OE160 specification, covering model years 2007 to 2011. It fits the rear axle only. Confirm your exact chassis variant and the OE160 designation against your car before ordering, and pair with the matching front kit if you want a full front-and-rear balance change.

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.
