XYZ Racing Hollow Rear Brake Kit — Infiniti G35 4D (2003-2006)

The V35 G35 saloon carries its weight differently to the coupe: a longer wheelbase, more mass over the rear axle, and a chassis that leans hard on its back tyres at corner exit once the VQ35 starts pulling. The rear axle is where heat builds on a track day, and the factory rear discs go soft long before the fronts are done. This XYZ Racing rear brake kit for the Infiniti G35 4D (2003-2006) replaces them with a larger vented setup built to take repeated stops without the pedal travelling long.

It is a rear-axle upgrade, not a styling job. A pair of larger two-piece floating discs, uprated calipers and a choice of pad compound let you rebalance braking on a rear-drive saloon that has always asked a lot of its back brakes under trail-braking and on downhill circuits.

What this rear big brake kit does for your 2003-2006 Infiniti G35 4D

On the road you get a firmer, more progressive pedal and shorter stops from cold, which is how a daily-driven G35 spends most of its life. On track the gain is consistency: the greater swept area and the hollow-vane rotors shed heat faster, so the bite you feel early in a session is still there after a run of hard braking zones. Run the Racing compound and initial bite sharpens for circuit use; the Street compound keeps dust and noise sensible for road work, with the Sport pad sitting between the two for fast road and the occasional track day. Because this is the rear axle, the real payoff is balance. More rear braking authority settles the car into a corner and trims the turn-in push that nose-led saloons show when only the fronts are working, and it works hand in hand with the front kit to share load between front and rear.

About the Hollow rear brake kit

XYZ Racing build this kit as a pair of larger two-piece floating discs and uprated calipers, with hollow-vane rotor castings that trim rotating and unsprung mass while keeping the internal vanes that drag heat out of a heavy saloon’s rear axle. Where the standard disc is sized for the factory’s expectations, this kit adds swept area and thermal headroom for harder, more repeated use. Three pad compounds are offered: Street, the quiet low-dust road default, Sport for fast road with more bite and heat range, and Racing for circuit and track-day work, so the kit can be specced to how the car is actually driven. The caliper is a hollow-body item as standard, and serious track users can step up to the Hollow Racing version, which 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; a Custom Color in any Pantone shade is available for £150, and premium polished-forged finishes (Titanium, Polished Gold, Polished Silver) or candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) are there if you want the hardware on show. Discs come drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable at checkout. It is a rear-specific kit cut for this chassis rather than a universal bracket-and-disc bundle, which is what keeps the fitment clean.

Fitment for the Infiniti G35 4D (2003-2006)

This kit is sized for the rear axle of the Infiniti G35 4D saloon built from 2003 to 2006, the V35-generation car. It is a pair of rear calipers and discs, so it pairs naturally with a matching XYZ Racing front kit if you want to upgrade both ends. Confirm your exact build year before ordering so the caliper and rotor match your car.
