XYZ Racing Hollow Rear Brake Kit — Infiniti Q70 Y51 FUGA M25/ M35 (2010-2019)

The Y51 Fuga rides on Nissan’s front-midship platform with the better part of 1.7 tonnes to haul down, and a comfort-biased factory brake set-up that was never asked to do repeat hard stops. On a heavy rear-drive saloon the back axle does more braking work than most owners credit, and it is usually the first thing to overheat once the car gets used in anger.

This XYZ Racing rear brake kit for the Infiniti Q70 Y51 FUGA M25/ M35 targets that weakness at the rear corners. It pairs a pair of larger two-piece floating discs with fixed calipers and a choice of three pad compounds, so you can set the rear thermal capacity to match how the car is actually driven, whether that is motorway miles, fast B-roads, or the occasional track day in a 3.5-litre M35.

What this brake kit does for your 2010-2019 Infiniti Q70 Y51 FUGA M25/ M35

After fitting, the gain shows up exactly where the standard rears struggle: heat. The larger rear rotors carry more thermal mass and their hollow-vane castings shed it faster, so the rear brakes hold their bite through repeated stops instead of going soft and stretching the pedal long. That matters on a car this heavy, where fade at the back unsettles the chassis mid-corner and saps your confidence to trail-brake into a turn. The three pad compounds, Street, Sport and Racing, let you bias the kit toward quiet daily manners, firmer fast-road bite or aggressive friction for circuit work without changing hardware. And because rear brake balance is part of how the Q70 rotates under braking, a consistent rear end makes the whole saloon feel more planted when you lean on it.

About the Hollow Rear Brake Kit

XYZ Racing builds this as a rear-axle pair of larger two-piece floating discs and fixed calipers, named for the hollow-vane rotor that runs cooler and lighter than a solid equivalent, trimming both rotating and unsprung mass at the back of the car. The fixed caliper resists flex under load, which is what keeps pedal feel firm where a tired sliding caliper would deflect and taper pad wear. Pads come in three compounds: Street for ordinary road use, Sport for harder fast-road driving, and Racing for sustained track temperatures, so the kit scales with intent rather than locking you into one character. The caliper is hollow-body 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. Calipers are painted at no extra cost in Red, Yellow, Gold, Black or Anodized Black, with a Custom Color in any Pantone for £150 and premium polished-forged (Titanium, Polished Gold, Polished Silver) or candy (Candy Teal, Candy Blue, Candy Red, Candy Orange) finishes available. Discs come drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable at checkout. Everything is sized to the Y51’s rear hubs.
