Caliper render for this kit:
The Y51 platform underpins one of the more capable large-saloon chassis Infiniti produced, a rear-wheel-drive layout with the 3.5-litre V6 mounted well behind the front axle centreline, giving the M35 and Q70 a composure most German contemporaries at this price point could not match. That composure is real, but the standard front braking hardware tells a different story. OEM calipers and rotors are calibrated for longevity and linear feel under light to moderate inputs, and under the kind of repeated hard deceleration a driver actually uses when the V6 is working, thermal loading becomes the limiting factor.
The XYZ Racing front big brake kit addresses that directly. The hollow-vane two-piece disc improves heat evacuation at the front axle, where weight transfer under braking concentrates the greatest load on a car of this mass, and three selectable pad compounds let the system be configured from daily commuting through to track attendance.
What this brake kit does for your 2010-2019 Infiniti Q70 Y51 FUGA M25/ M35
The hollow-vane disc pulls heat away from the pad-disc interface faster than a conventional vented rotor, reducing the pedal lengthening and bite degradation that appears when the OEM front brakes are worked hard in succession. On a car weighing close to 1,800kg in M35 specification, that thermal margin is the difference between consistent stopping distances and creeping fade across repeated hard applications. The two-piece construction also trims rotating and unsprung mass at the front corners, and the floating bell keeps the disc flat as it heats.
The three pad compounds calibrate the system to the owner’s actual use. Street is the quiet, low-dust road default, keeping dust and noise down for daily driving. Sport sharpens initial bite and widens the heat range for spirited road use and the occasional track day. Racing handles sustained heat where maximum thermal tolerance is the requirement. Braided lines are included for a firmer, more consistent pedal.
About the front big brake kit
The kit pairs a hollow-body forged caliper as standard with a two-piece floating disc that raises thermal capacity beyond what a conventional disc of equivalent size can manage. The vane geometry increases the effective surface area exposed to airflow, accelerating heat dissipation both during and between applications. 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 sustained hard use, the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C and carries a two-year warranty. The kit covers the front axle of the Y51 platform, targeting the axle that manages the largest share of braking energy.
Fitment for the Infiniti Q70 Y51 FUGA M25/ M35 (2010-2019)
This front brake kit covers the Y51 chassis throughout its full production run: the M25 and M35 variants from 2010 through to the 2014 Q-series rebadge, and the Q70 that continued on the same architecture through to 2019. The FUGA designation is the Japanese-domestic-market name for the same Y51 platform. Confirm your front caliper mounting configuration against the supplied installation specification before fitting.

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.
