Fits Toyota CELICA ST185 (1989-1993)

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 CELICA ST185 (1989-1993) — 330 mm
330 mm

The ST185 GT-Four puts its 3S-GTE turbo power down through all four wheels, and that full-time all-wheel-drive layout means the rear axle works harder under braking than a front-biased weight figure suggests. The XYZ Racing Hollow Rear Brake Kit for the Toyota Celica ST185 (1989-1993) addresses the rear end specifically: more thermal headroom and a firmer pedal for a car that still gets driven hard three decades after it took Sainz to two world titles.

On a homologation-era rally platform like this, the standard rear setup was specified for a 1990s road car, not for repeated heavy stops on a track day or a committed B-road. Supplied as a matched pair of rear calipers and two-piece floating discs, this kit gives the ST185’s rear axle the capacity to brake late and stay consistent, with pad compound, disc style and caliper colour chosen to suit how you actually use the car.

What this brake kit does for your 1989-1993 Toyota Celica ST185

Fit this rear kit and the first thing you notice on the ST185 is brake balance you can lean on. The two-piece floating disc trims rotating and unsprung mass at the rear axle, which helps the GT-Four’s all-wheel-drive chassis settle on corner entry rather than squatting and pushing. Three pad compounds let you match bite and temperature range to your use: Street for low-dust road commuting, Sport for harder fast-road work with the odd track day, and Racing for back-to-back circuit sessions. The Racing compound holds friction when the rear discs are hot, so the pedal stays firm deep into a braking zone instead of going long. For a Toyota Celica ST185 that splits its life between the road and the occasional track, that is the difference between guessing the brake point and knowing it.

About the Hollow rear brake kit

XYZ Racing’s rear brake kit for the Celica is built around a hollow-vane disc, where material is removed internally to shed rotating mass without giving up swept area or heat capacity. The result is a rotor that comes up to temperature quickly and sheds it just as readily, which matters on a turbocharged AWD car that carries speed into corners; the disc is two-piece and floating, with a lighter alloy bell. The caliper is hollow-bodied as standard, with an optional Hollow Racing upgrade that drops the dust cover, is rated to 1000C and carries a two-year warranty for serious track use.

The kit is offered with three friction levels: a Street compound for quiet, low-dust road use, a Sport compound with more bite for fast-road work, and a Racing compound built for sustained high-temperature work. Calipers are finished in your choice of 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 or polished silver, and candy finishes in teal, blue, red or orange, so the rear of the car reads as a considered build rather than a bolt-on. Discs are drilled or slotted at the same price, and the centre bell can be upgraded to two-tone anodized in five colours or titanium. It is engineered as a direct-fit rear upgrade for the ST185, not a universal kit shimmed to suit.

Fitment for the Toyota Celica ST185 (1989-1993)

This kit fits the rear axle of the Toyota Celica ST185, the GT-Four generation built from 1989 to 1993, and is supplied as a matched left-and-right pair. Confirm your car carries the ST185 chassis code before ordering, as the contemporary front-drive ST182 and ST183 Celicas use different rear hardware. Caliper colour, disc style and pad compound 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.
