Caliper render for this kit:

The A90 Supra’s BMW-derived multi-link rear axle does more braking work than most owners expect. On a short 2470mm wheelbase the car stays lively into a corner, and trail-braking loads the rear discs hard enough that the standard setup starts to glaze on a second or third hot lap. The XYZ Racing Hollow Rear Brake Kit for the Toyota Supra (J29/ A90) is built to take that heat without going wooden underfoot.
This is a rear-axle upgrade, not a styling exercise. The hollow-vane disc strips rotating and unsprung mass off the back of the car, which sharpens how the Supra settles under braking and frees the rear suspension to work over kerbs and mid-corner bumps. With Street, Sport and Racing pad compounds offered, you spec the bite to suit whether the car sees the daily commute, a B-road blast or a full track day.
What this big brake kit does for your 2019-2026 Toyota Supra (J29/ A90)
On the 2019-2026 Toyota Supra the first thing you feel is a firmer, more consistent rear pedal as temperatures climb, and the fade that creeps in late in a session is pushed much further back. The two-piece floating disc and its hollow-vane core cut rotating mass, so the rear axle reacts faster to pedal inputs and the car feels more planted when you brake deep into a turn. Step up to the Racing compound for sharp initial bite on circuit, run the Sport pad for fast-road work with the heat range for occasional track use, or keep the Street pad for quiet, low-dust daily driving. Better rear thermal capacity also helps the balance, taking load off the fronts so the whole package stays predictable when you push.
About the Hollow Rear Brake Kit
The XYZ Racing Hollow Rear Brake Kit is a rear big brake conversion built around lighter two-piece floating discs and a matched caliper. The hollow-vane disc core is what reduces rotating mass and helps shed heat, without sacrificing the swept area that does the actual stopping. The kit is offered with three pad compounds: a Street pad for quiet road use, a Sport pad for harder fast-road and occasional track work, and a Racing pad for sustained circuit sessions. The caliper is hollow-bodied as standard for stiffness, with a Hollow Racing upgrade for serious track use that drops the dust cover, is rated to 1000C and carries a two-year warranty. Included colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with premium polished-forged finishes in Titanium, Polished Gold and Polished Silver, candy finishes in Teal, Blue, Red and Orange, or any Pantone as a custom colour. Choose drilled or slotted faces at the same price, and a two-tone anodized or titanium centre bell at checkout. It is engineered as a direct-fit rear application for the Supra rather than a universal kit shimmed to suit.
Fitment for the Toyota Supra (J29/ A90) (2019-2026)
This kit is the rear-axle application for the J29 / A90 Toyota Supra built from 2019 to 2026. It fits the rear position only, supplied as a left-and-right pair matched to the Supra’s factory rear hub geometry. Confirm your build year sits inside the 2019-2026 range before ordering, and pair it with a front kit if you want a matched setup front to rear.

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.
