Fits Toyota GT86 (2012-2020)

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 — Toyota GT86 (2012-2020) — 330 mm
330 mm

The Toyota GT86 rewards a driver who brakes deep and rotates the car on the way to an apex, and that style leans hard on the rear axle. The standard ZN6 rear brakes were specified for a 200bhp road car running modest factory rubber, not for a hot lap or a long stint of throttle-off rotation. This XYZ Racing Hollow Rear Big Brake Kit for the Toyota GT86 (2012-2020) gives the back of the car the thermal headroom that driving style actually needs.

Built around lighter two-piece floating discs and a fixed caliper, it sharpens rear bite and holds a steadier pedal once the rears start doing real work. On a car this committed to front-to-rear balance, the rear end is not an afterthought. It is where a GT86 earns or loses its lap time, and this kit is a left-and-right rear pair sized to lift it.

What this brake kit does for your 2012-2020 Toyota GT86

The first thing you feel is a rear axle that stops fading mid-session, so brake balance stays where you set it instead of creeping forward as the standard discs heat-soak. Pad compound is your tuning lever here: the Street option keeps things quiet and low-dust for the commute, Sport steps up bite and heat range for spirited road and occasional track use, and Racing gives you the friction and fade resistance for repeat hard braking on circuit. Because the GT86 trail-brakes its way into rotation, a more confident rear end translates directly into a more predictable car at turn-in. Fit the Racing compound and you get a firmer response at temperature that suits left-foot braking and aggressive entry without the rears going greasy.

About the Hollow Rear Brake Kit

The Hollow name refers to the caliper, a hollow-body casting fitted as standard with internal voids that cut weight at the corner while keeping the housing stiff. It clamps a vented two-piece floating rotor that moves cooling air through the disc and trims rotating mass at the rear corners, paired with the fixed caliper for a stiffer, more consistent pedal than the sliding factory setup. Three pad compounds ship as options, Street, Sport and Racing, so the same hardware suits a daily GT86 or a dedicated track tool. Discs come drilled or slotted at the same price, with two-tone anodized or titanium centre bells when you order. Painted calipers are offered 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 to match your build, and a Hollow Racing caliper rated to 1000C for the hardest track use. It is a rear-specific kit, engineered to lift the weaker end of the GT86’s braking system rather than simply replace consumables.

Fitment for the Toyota GT86 (2012-2020)

This kit fits the first-generation Toyota GT86 on the ZN6 chassis, covering the full 2012-2020 model run before the GR86 took over. It is a rear-axle fitment supplied as a left-and-right pair and pairs naturally with a matching front kit if you are upgrading both ends of the 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.
