Caliper render for this kit:

The Giulia 952 was built around balance. The Giorgio platform’s near 50:50 distribution and a composed rear axle are the reasons enthusiasts keep choosing it over a 3 Series. What that balance asks for, once you start leaning on it on a fast B-road or a track day, is a rear brake that resists fade as stubbornly as the front. The XYZ Racing Hollow Rear Brake Kit answers that for the 2.0 petrol Giulia, including the Q4 four-wheel-drive cars that carry more mass over the axle.
This kit is engineered around the Giulia’s electronic parking brake, so the EPB function and hill-hold carry over without workarounds, a real consideration on this chassis where the rear caliper does double duty. It is a matched pair of left and right rear calipers and two-piece floating discs, pairing a lighter hollow-vane disc with a higher-clamp caliper to give the rear axle the thermal headroom the standard setup runs short of under repeated heavy stops.
What this brake kit does for your 2015-2026 Alfa Romeo Giulia
The first thing you feel after fitting is a firmer, more consistent pedal when the discs are hot, exactly the point where the factory rear brakes on a worked Giulia start to go long. The hollow-vane disc core trims rotating mass at the rear, which sharpens how quickly the car settles under trail-braking into a corner. Because the kit keeps the electronic parking brake, none of this costs you the EPB you rely on day to day.
Pad compound matches the kit to use. Street is the quiet, low-dust road default. Sport adds bite and heat range for spirited road plus the odd track session. Racing is the full track compound with bite from cold during full lapping. Caliper finish comes in the included Red, Yellow, Gold, Black or Anodized Black, with any Pantone available as a Custom Color.
About the Hollow Big Brake Kit
The Hollow Rear Brake Kit is XYZ Racing’s rear upgrade for the Giulia 952, built on two-piece floating discs with a hollow-vane core that sheds weight without surrendering swept area or thermal capacity. The lighter rotating assembly reduces unsprung and rotational mass at the rear axle, which helps both ride compliance and how promptly the brakes respond. The caliper is designed to deliver higher, more even clamping force than the OE rear unit, and crucially to integrate the car’s electronic parking brake rather than delete it.
Disc face is drilled or slotted at the same price, and centre bell upgrades, two-tone anodizing in five colours or titanium, are selectable when you order. Pad choice spans Street, Sport and Racing, so the same hardware covers a daily-driven 2.0 petrol Giulia and a car that sees regular track time. The caliper is hollow-body as standard, with premium polished-forged Titanium, Polished Gold and Polished Silver and candy Teal, Blue, Red and Orange beyond the included colours. A Hollow Racing caliper, with no dust cover, a 1000C rating and a two-year warranty, is there for serious track use. It is a rear-axle kit intended to balance a front upgrade or to cure the rear fade that limits hard, repeated braking on the standard discs.

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.
