Caliper render for this kit:

The Nissan 370ZX Z34 carries a torque-rich 3.7-litre V6 and real mass over the front axle, and on a circuit that combination punishes the standard rear brakes long before the fronts cry off. The XYZ Racing rear big brake kit for the 370ZX Z34 (2009-2026) attacks that weak point directly, adding thermal headroom and a firmer, more predictable pedal at the rear, where this heavy RWD coupe generates much of its rotation.
This is a single rear-axle kit, a matched pair of rear calipers and two-piece floating discs, so it works alongside your front setup to rebalance how the car sheds speed. Match the pad compound to how you actually drive (Street for the road, Sport for fast-road and occasional track, Racing for sustained circuit sessions) and the back of the 370ZX stops being the first thing to fade.
What this brake kit does for your 2009-2026 Nissan 370ZX Z34
Fit the kit and the first thing the Z34 gives back is a rear brake that no longer fades to a long pedal after three hard laps. A larger rear rotor and uprated caliper add the thermal mass the standard parts lack, so repeated heavy stops stay consistent rather than spongy. The hollow-vane, lightweight rotor trims rotating and unsprung weight at the rear, which sharpens turn-in and helps the dampers keep the wheel planted over kerbs. Because you choose the pad compound, you can set rear bite for road manners or for circuit aggression. The included caliper finishes, Red, Yellow, Gold, Black and Anodized Black, plus a Custom Color in any Pantone and premium options, mean the upgrade reads behind the wheels as clearly as it works under braking.
About the rear big brake kit
A big brake kit is more than a bigger disc; it is a matched rotor-and-caliper package sized to put thermal capacity where the heat actually goes. This rear kit centres on a hollow-vane, lightweight two-piece floating rotor that sheds rotating mass while keeping the swept area needed to absorb energy on a coupe as heavy as the 370ZX Z34. The hollow-bodied caliper clamps a wider pad than standard, and three compound choices, Street, Sport and Racing, let you tune the friction level and operating-temperature window to your use. Street suits everyday road driving, Sport steps up bite and fade resistance for fast-road and light track work, and Racing is built to take sustained circuit heat. Discs come drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable when you order. The included caliper colours, plus a Custom Color in any Pantone and premium polished-forged and candy finishes, complete the package.
Fitment for the Nissan 370ZX Z34 (2009-2026)
This kit is cut for the Z34-generation Nissan 370ZX, covering the full 2009 to 2026 production span. It fits the rear axle specifically, so decide whether you are also uprating the front to keep brake balance where you want it. Choose your pad compound and caliper colour from the options above to suit your build.

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.
