Fits Tesla MODEL X (OE SINGLE-SIDE WITH ONE CALIPER) (2015-2020)

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 — Tesla MODEL X (OE SINGLE-SIDE WITH ONE CALIPER) (2015-2020) — 380 mm
380 mm

Two and a half tonnes of dual-motor Model X carries more mass over the rear axle than almost anything the standard rear brakes were sized to stop, and that gap only shows itself on the second or third hard stop. The XYZ Racing Hollow Rear Big Brake Kit replaces the OE single-side, single-caliper rear setup on the 2015-2020 Tesla Model X with a system built to absorb that heat rather than soak it up and fade.

This is rear-axle hardware for owners running their Model X harder than the school run: repeated high-speed slowing on a B-road, the occasional track day, or simply wanting a heavy electric SUV to feel composed when the regen tapers off and the friction brakes have to do the work alone. A front and rear pairing keeps the balance honest, but this kit covers the rear axle on its own as a matched pair of rear calipers and two-piece floating discs.

What this brake kit does for your 2015-2020 Tesla Model X

On a car this heavy, regenerative braking flatters the standard pedal until you ask for repeated hard stops, at which point thermal capacity becomes the whole story. This kit gives the rear axle more material to push heat into, so the Model X holds a firmer, more predictable pedal when the regen has handed everything back to the discs. The two-piece floating discs run a lighter alloy bell, trimming rotating and unsprung mass at the rear so the dampers settle the back of the car more quickly over broken surfaces.

You choose the bite to suit the use. The Street compound is the quiet, low-dust road default. Sport adds more bite and a wider heat range for fast-road work and the occasional track day. Racing is the full track compound for sustained circuit abuse. Caliper finishes read through the wheel as deliberately as they perform: Red, Yellow, Gold, Black and Anodized Black are included at no extra cost, with a Custom Color in any Pantone shade available, and premium polished-forged or candy finishes for owners who want the calipers to be the centrepiece.

About the Hollow Rear Big Brake Kit

The "Hollow" in the name refers to the lightened hollow-vane disc, which trims rotating mass at the rear while keeping the swept area needed to manage heat on a heavy platform. It supersedes the OE single-side, one-caliper rear arrangement with a properly specified caliper and two-piece floating disc package intended for sustained load rather than light-duty stops.

The caliper body is hollow as standard, and serious track users can step up to the Hollow Racing caliper, which drops the dust cover, is rated to 1000C and carries a two-year warranty. Pad material is a deliberate choice rather than a fixed compromise, with Street, Sport and Racing compounds covering everything from daily use to circuit sessions. Discs 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. It is a rear-specific kit, designed to balance against a front upgrade rather than work in isolation.

Fitment for the Tesla Model X (2015-2020)

This kit is cut for the 2015-2020 Tesla Model X running the OE single-side rear caliper configuration. It is a rear-axle fitment only, supplied as a matched left-and-right pair, so confirm your front setup separately when planning the full upgrade. Pad compound, disc style, caliper colour and centre-bell finish are all selected at checkout.

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.
