Caliper render for this kit:
The E36 generation moved the 3 Series onto BMW’s multi-link Z-axle rear end, a real step on from the E30’s semi-trailing arms, but the standard rear discs on the 325 were sized for road duty, not repeat heavy braking. Push the car on a circuit and the rear axle is usually the first to lose heat capacity, which shifts brake balance forward and unsettles the chassis exactly when you are leaning on it through a corner.
This XYZ Racing Hollow Rear Brake Kit for the BMW 3 Series E36 325 attacks that weak point directly. It is a rear-axle big brake kit supplied as a left-and-right pair, built to restore the front-to-rear balance the standard setup gives up under load, with pad compound choices that let you match the car to road, fast-road or circuit use.
What this brake kit does for your 1990-1998 BMW 3 Series E 36 325
Fit this kit and the clearest gain is a rear axle that stops fading after a handful of hard stops, so the car holds the same pedal feel and the same balance from your first stint to your last. The two-piece floating disc and its hollow-vane rotor trim rotating and unsprung mass at the back, which the multi-link rear rewards with crisper turn-in response and an easier job for the dampers. Three pad compounds, Street, Sport and Racing, let you run a quiet, low-dust setup for daily driving or step up to the Racing compound for track days without changing any hardware. On a 325 that does both jobs, that swap-without-strip flexibility is the whole point.
About the Hollow Rear Brake Kit
The Hollow Rear Brake Kit is XYZ Racing’s rear-axle upgrade, named for the hollow-vane rotor on its two-piece floating disc that cuts mass where the standard cast discs carry it needlessly. Larger, better-ventilated discs raise the thermal ceiling so heat builds more slowly and sheds faster between braking events, the single biggest factor in fade resistance. The caliper clamps a wider, more consistent pad face, and the kit is supplied with a choice of three pad compounds spanning road manners through to track bite. Disc faces are available drilled or slotted at the same price. Calipers come painted in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any Pantone, premium polished-forged finishes in Titanium, Polished Gold and Polished Silver, and candy Teal, Blue, Red and Orange, so what sits behind the wheel matches the rest of the build. It is engineered as a bolt-on package for the E36 platform rather than a universal fit-and-hope part.

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.
