Caliper render for this kit:

The 1999-2003 Commodore 160 is a heavy rear-drive saloon, and on a hard-used car it is the rear axle that quietly takes the punishment: repeated stops from speed, a loaded boot, and the independent rear end working through every corner. The standard rear discs cope with shopping-run duty, but they run out of thermal headroom long before the front end does once you start using the car. The XYZ Racing rear brake kit is built to put that headroom back.
This is a rear big brake kit aimed at owners who track, sprint, or simply drive their Commodore the way it was meant to be driven. It adds rotor mass and caliper clamping where the factory setup is weakest, so the rear stays composed when the brakes are hot and the bias stays where you set it.
What this brake kit does for your 1999-2003 Holden Commodore 160
Fit it and the first thing you notice is a firmer, more progressive rear bite, the kind that lets you trail-brake into a corner without the back stepping out of line. The larger two-piece floating rotors carry and shed heat better than the originals, which keeps pedal feel consistent across repeated stops instead of going long and vague after three hard laps. Pad compound is your call: Street is the quiet, low-dust default for daily use, Sport adds bite and heat range for fast-road work, and Racing is the dedicated track compound for when the car spends real time at temperature. On a 1600kg-plus saloon, that extra rear thermal capacity is what stops a track session ending early.
About the Rear Brake Kit
The two-piece floating rotor is the engineering point here, supplied as a matched pair for the rear axle. Internal hollow vanes cut mass out of the disc to reduce rotating and unsprung weight at the back, which sharpens response and eases the load on the rear suspension without giving up swept area, and the discs come drilled or slotted at the same price. The kit pairs those rotors with uprated calipers and runs the three-stage pad menu: Street for quiet road use, Sport for fast-road bite, and Racing for sustained track heat. The hollow-body caliper is standard, with an optional Hollow Racing upgrade for serious track use that drops the dust cover, is rated to 1000C and carries a two-year warranty. Included painted finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a custom Pantone colour at £150, plus premium polished-forged Titanium, Polished Gold and Polished Silver and candy Teal, Blue, Red and Orange. It is a bolt-on rear upgrade engineered specifically around the Commodore’s rear hub and disc dimensions.

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.
