Caliper render for this kit:

The E90 M3 carries a 4.0-litre S65 V8 over its front axle and drives the rear wheels, so the back brakes spend much of their working life managing weight transfer rather than scrubbing the headline speed. XYZ Racing’s Hollow Rear Brake Kit for the BMW 3 Series E90 M3 (2007-2011) swaps the factory rear assembly for a larger, lighter setup that keeps the car settled when the standard discs start to heat-soak.
This is the rear half of the braking equation on the saloon-bodied M3, the four-door that hides a rev-hungry V8 behind an unassuming boot lid. Push one hard on track or a committed B-road and the rear axle needs discs that recover between stops and hold a steady bite under trail braking. Supplied as a left-and-right pair, that is the job this kit is built around.
What this big brake kit does for your 2007-2011 BMW 3 Series E90 M3
The headline gain is heat capacity. A larger rear disc gives the M3 more thermal mass to soak up repeated heavy stops, so the pedal stays firm deep into a session instead of going long as the fluid and friction surfaces cook. The two-piece floating disc and its hollow-vane rotor trim rotating and unsprung weight at the rear, which sharpens how quickly the axle responds to direction changes and takes load off the dampers. Three pad compounds, Street, Sport and Racing, let you match the rear bite to how the car is actually used, from quiet, low-dust road miles to full track abuse. Because the caliper comes in Red, Yellow, Gold, Black, Anodized Black or a Custom Color, the upgrade reads as cleanly through the spokes as it performs.
About the Hollow Rear Brake Kit
This is a bolt-on rear big brake upgrade engineered around the E90 M3’s rear hubs rather than a universal part forced to fit, and supplied as a pair. The defining feature is the two-piece floating disc, whose hollow-vane rotor sheds rotating mass while keeping a large swept area for heat management. The hollow-body caliper clamps a wider, thicker rotor than the factory item, raising the temperature ceiling before fade sets in. Pad material is a choice rather than a fixed spec: the Street compound suits quiet road use, the Sport compound adds bite for fast-road and occasional track work, and the Racing compound is there for sustained circuit sessions. Disc faces can be drilled or slotted at the same price, caliper finishes cover everything from a discreet Black through to a louder Gold or a Custom Color in any Pantone, and a Hollow Racing caliper upgrade rated to 1000C is on hand for dedicated competition use.
Fitment for the BMW 3 Series E90 M3 (2007-2011)
This kit is built for the E90 saloon M3 across the 2007 to 2011 production span, mounting at the rear axle as a left-and-right pair. It is a rear-axle kit, designed to pair with a matching front big brake setup or run alongside the factory fronts. Confirm your exact chassis code and build year before ordering.

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.
