Caliper render for this kit:
The S51-generation FX37 is around two tonnes of luxury crossover with a 3.7-litre VQ37VHR that pulls hard from low in the rev range, a combination that places serious, repeated demand on the front axle the moment the road gets interesting. Infiniti’s factory front brake specification was calibrated for refinement and long service intervals, not the sustained hard braking that comes with fast B-road work or downhill runs where you are on the pedal early and often. Under those conditions the OEM setup runs short of thermal headroom.
This XYZ Racing front big brake kit for the FX37 3.7 V6 S51 (2013-2017) replaces the stock front assembly with a setup built around what the FX37 actually asks of its brakes. It is a front-axle kit, a matched left and right pair of calipers and two-piece floating discs. Three pad compounds, Street, Sport and Racing, and a full caliper colour menu mean the specification can be matched to how the car is genuinely driven, all chosen when you order.
What this brake kit does for your 2013-2017 Infiniti FX37 3.7 V6 S51
The FX37’s elevated ride height transfers more mass forward under deceleration than a saloon of similar weight, which concentrates braking energy at the front axle. The hollow-vane disc moves heat away from the disc surface more efficiently than a solid unit, keeping pad-to-disc temperatures within range when the brakes are working repeatedly in a short stretch of road, and the two-piece floating construction keeps the iron ring flat as it heats. Sport gives stronger initial bite and better high-temperature recovery than the factory pads without the cold-bite penalty that makes a race compound impractical on a road car through UK winters; Street stays quiet and low-dust; Racing handles the extended thermal loading that hard road driving or track days generate. For owners who push the FX37 across extended fast driving days, this kit turns the front brakes from a thermal-management concern into a stable, confidence-building part of the car. Included caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone.
About the Hollow Front Brake Kit
The hollow-vane disc draws airflow through its internal structure under load and lowers the thermal ceiling the system works against during sustained use, available drilled or slotted at the same price. The caliper is a hollow-body forging as 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. Three pad compounds address the full range of use: Street prioritises low dust and fade resistance for daily driving with occasional enthusiasm; Sport shifts the balance toward stronger bite and quicker recovery; Racing is formulated for extended thermal loading. Caliper colour extends beyond the painted finishes to premium polished-forged Titanium, Polished Gold and Polished Silver and candy Teal, Blue, Red and Orange, with two-tone or titanium centre bells, all selectable at checkout, so the finished installation presents correctly behind the FX37’s substantial alloys. The front-axle focus targets the upgrade point that matters most on the S51 platform, where the crossover body’s weight transfer under braking makes the front a clear priority.

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.
