XYZ Racing Hollow Rear Brake Kit — Infiniti FX37 3.7 V6 S51 (2013-2017)

The S51 FX37 hides its mass well until you brake hard from speed: close to two tonnes of nose-heavy, all-wheel-drive crossover asks a great deal of the rear axle, and the factory rear discs are the first thing to wilt on a repeated stop. This XYZ Racing Hollow Rear Brake Kit for the Infiniti FX37 3.7 V6 targets exactly that weakness, adding heat capacity and bite where the standard setup gives up first.

It is rear-axle hardware meant to rebalance a front big brake upgrade or to claw back stopping authority the FX37 loses as it ages. The hollow-vane rotor sheds heat and rotational mass, and three pad compounds let you match the kit to road, fast-road, or circuit duty.

What this brake kit does for your 2013-2017 Infiniti FX37 3.7 V6 S51

On a crossover this heavy, the rear brakes are doing more work than the spec sheet implies, and that work turns to heat fast. The hollow-vane rotor vents that heat more readily than a solid factory disc, so the pedal stays firm through a sequence of hard stops rather than going long and soft. Cutting rotational and unsprung mass behind the FX37’s large-diameter wheels also sharpens how the back end settles under braking, steadying a tail that can feel busy when you trail the brakes into a corner. With the VQ37VHR’s pace on tap, that extra rear-axle composure is what keeps the whole car planted. The pad choice runs Street for quiet, low-dust daily use, Sport for fast-road heat range, and Racing for circuit temperatures, while the caliper colours let the hardware read clearly through open-spoke wheels.

About the Hollow Rear Brake Kit

The defining feature is the hollow-vane rotor: an internally vented disc whose construction trims weight while opening up cooling paths that a stock rear disc lacks. The two-piece floating rotors run cooler still, and the caliper body is hollow as standard. Paired with an uprated rear caliper, it raises the heat ceiling on an axle that the factory undersized for sustained hard use. Three pad compounds ship as options, Street for quiet everyday road manners, Sport for harder fast-road work, and Racing for circuit temperatures where outright fade resistance matters most. Discs come drilled or slotted at the same price. The kit is a rear-specific pair of discs and calipers, designed to be run alongside a front upgrade so the FX37’s braking balance stays honest front to back. Caliper finishes cover Red, Yellow, Gold, Black and Anodized Black at no extra cost, with premium polished-forged Titanium, Polished Gold and Polished Silver, candy Teal, Blue, Red and Orange, or any Pantone shade as a custom colour, covering the cosmetic side without changing the engineering brief.
