Fits Toyota MARK X (X120) (2004-2009)

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 — Toyota MARK X (X120) (2004-2009) — 330 mm
330 mm

The MARK X X120 was built as a refined rear-drive saloon, and its factory rear brakes were sized for that brief: steady motorway stops, not repeated hard use. Push a GRX120-series car on a quick B-road or a track day and the rear axle is the first to heat-soak, which is exactly where this XYZ Racing Hollow Rear Brake Kit for the Toyota MARK X (X120) earns its place.

This rear kit lifts the back axle’s thermal capacity and pedal consistency without unsettling the car’s RWD balance. The two-piece floating disc design sheds heat and trims rotating mass, so the rears stay composed through the kind of repeat braking that leaves a standard 2004-2009 MARK X feeling soft and vague. It is supplied as a left-and-right rear pair.

What this brake kit does for your 2004-2009 Toyota MARK X (X120)

After fitting, the first thing you notice is a firmer, more repeatable pedal. The rear axle stops going soft under load, so the car’s braking balance holds even after several hard stops in a row. On a rear-drive saloon like the MARK X X120, stable rear braking also helps the car settle and rotate on trail-braking into a corner rather than washing wide. The two-piece discs run cooler, which protects pad life and keeps the rear from overheating during spirited driving. With three pad compounds, Street, Sport and Racing, you can match the rear bite to how hard you actually drive, from quiet daily use to circuit work. Painted caliper finish is yours to set, in Red, Yellow, Gold, Black or Anodized Black, or a Custom Color in any Pantone.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit runs a hollow-body caliper as standard, cast with internal voids to cut weight at the corner while staying rigid. It clamps a two-piece floating rotor that removes material to drop rotating and unsprung mass while opening up extra surface for heat to escape. Less rotating mass at the rear axle means the brakes shed temperature faster and recover quicker between applications, which is the whole point on a heavier V6 saloon. The kit is offered with three pad compounds: a Street compound for quiet, low-dust road use, a Sport compound for harder fast-road driving, and a Racing compound for track work. Discs come drilled or slotted at the same price, with two-tone anodized or titanium centre-bell upgrades. Painted calipers come in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any Pantone and premium polished-forged and candy finishes, so the look matches the rest of the build, and a Hollow Racing caliper rated to 1000C is available for the hardest use. It is a rear-axle kit, designed to work alongside the front brakes to restore proper front-to-rear balance once you start asking more of the car.

Fitment for the Toyota MARK X (X120) (2004-2009)

This kit is built for the Toyota MARK X (X120), covering the 2004 to 2009 GRX120-series model years. It is a rear-position fitment specific to the X120 chassis, supplied as a left-and-right pair. Confirm your chassis code and year against the listing before ordering, then choose pad compound and caliper colour to suit your car.

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.
