Fits Rolls-royce PHANTOM (2017-2026)

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.

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 — Rolls-royce PHANTOM (2017-2026) — 380 mm
380 mm

The Phantom VIII carries well over two and a half tonnes on its aluminium spaceframe, and the rear axle does the quiet, unglamorous work of hauling all of that mass down from a cruise. That is a hard brief: shed serious kinetic energy repeatedly without ever letting a shudder or a long pedal reach the cabin. The XYZ Racing Hollow Rear Brake Kit for the Rolls-Royce Phantom (2017-2026) is built for exactly that load case.

This is a rear-axle package, fitted as a matched pair, designed around two-piece floating discs that take weight out of the corner the Phantom can least afford to load – the unsprung mass at the wheel. Pad compound runs from Street through Sport to a full Racing spec, so the same kit can be specified for a chauffeur-smooth town car or for an owner who actually leans on the brakes.

What this brake kit does for your 2017-2026 Rolls-Royce Phantom

The first thing you feel is consistency. A car this heavy turns a single hard stop into a lot of heat, and standard discs soak that up and then start to fade on the second and third application. The two-piece floating disc carries more thermal headroom, so repeated braking from motorway speeds holds a firmer, more predictable pedal, and the floating mount keeps the rotor true as it heats. Cutting unsprung weight at the rear also lets the air suspension keep the body settled, protecting the ride the Phantom is bought for. Pad compound is the lever you pull for character: Street for serene town use, Sport for sharper bite on a fast A-road, Racing when heat is the limiting factor. Caliper colour – red, yellow, gold, black or anodized black at no extra cost, with a Pantone Custom Color for £150 – finishes the look behind the rear wheels.

About the Hollow Rear Brake Kit

The disc is a two-piece floating item: internal voids cast or machined into the rotor to lower rotating and unsprung mass without giving up the swept area a 2,500kg saloon needs, with the rotor running on its bell so it can grow under heat without distorting. Less mass means the disc accepts and releases heat faster and gives the rear suspension less inertia to control over broken surfaces. The kit fits at the rear axle only and is offered with three pad compounds – Street, Sport and Racing – so the friction level matches how the car is actually used. 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. Caliper finishes cover factory-discreet black through to gold or a Pantone Custom Color, with premium options alongside, and an optional Hollow Racing caliper – no dust cover, rated to 1000C, two-year warranty – is there for the hardest duty. It is a focused rear upgrade rather than a full overhaul, aimed at the heat management and pedal feel that the Phantom’s weight demands.

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.
