Caliper render for this kit:
The P71A QX50’s variable-compression VC-Turbo sits well forward of the front axle, a heavy and sophisticated unit that loads the front brakes with more mass than the factory specification was designed to manage enthusiastically. Infiniti built the original brake sizing around typical crossover use, which means the front discs run short of capacity on sustained descents or repeated hard stops on fast A-roads. The XYZ Racing front big brake kit replaces the front-axle hardware on the 2018-2026 QX50 with two-piece floating discs and a choice of pad compound that spans daily driving through to circuit use.
The two-piece floating disc reduces unsprung and rotating mass at the front axle while improving the disc’s ability to shed heat through its cross-section, two benefits that compound under exactly the use the factory setup finds uncomfortable.
What this brake kit does for your 2018-2026 Infiniti QX50
The QX50 P71A carries meaningful front-axle weight, between the VC-Turbo engine and the AWD hardware where fitted, and the factory front discs feel that load as temperatures climb. The hollow-vane two-piece disc dissipates heat faster through the disc itself, delaying the onset of fade that standard cast rotors exhibit when worked repeatedly. The floating bell lets the rotor expand evenly under load, keeping it true and the pedal consistent. Braided lines come as part of the kit for a firmer feel.
Three pad compounds let the specification match actual use. Street is the quiet, low-dust road default that handles everyday braking and fast-road miles without elevated noise. Sport adds bite and heat range for harder driving with the occasional track day. Racing tolerates the temperatures the QX50 builds on a circuit. You select the compound when you order.
About the front big brake kit
The hollow-body forged caliper is standard, paired with a two-piece floating disc whose construction removes material from within the rotor’s cross-section rather than from the swept face, preserving the structural integrity of the friction surface while cutting rotating mass at the hub. Less rotational inertia lets the front suspension respond more freely, feeding back as slightly sharper steering feel alongside the thermal benefit. Discs are offered drilled or slotted at the same price, and centre bell upgrades come as two-tone anodizing in five colours, or titanium, selectable at checkout.
Included painted caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost. Custom Color in any Pantone is £150. Premium polished-forged finishes cover Titanium, Polished Gold and Polished Silver, with a premium candy range of Candy Teal, Candy Blue, Candy Red and Candy Orange. For serious circuit work, the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C and carries a two-year warranty.
Fitment for the Infiniti QX50 (P71A) (2018-2026)
This kit covers the front axle of the P71A-generation QX50 across the full 2018 to 2026 model year span. Front brake geometry on the P71A is consistent across front-wheel-drive and AWD drivetrain variants, so fitment applies regardless of which driveline your car runs. Confirm your chassis falls within the 2018-2026 production window before selecting pad compound and caliper colour.

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 286–380mm (front). 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.
