XYZ Racing Hollow Rear Brake Kit — Infiniti G37 (2009-2013)

Most owners reach for bigger fronts first, but the V36 Infiniti G37 makes a real case for starting at the back. At the better part of 1,700kg, with a torquey 3.7-litre VQ V6 and a chassis tuned more for refined GT cruising than circuit aggression, the G37 leans hard on its brakes once you start using the performance it has, and the rear axle, doing quieter work, is where heat and fade creep in unnoticed on the heavier G37x and the convertible.

The XYZ Racing rear big brake kit targets exactly that. It gives the back axle more thermal headroom and a firmer, more consistent bite, so the rear stays settled and the car’s balance holds up when the fronts are working their hardest.

What this big brake kit does for your 2009-2013 Infiniti G37

On the road the first change is a more progressive, better-supported rear pedal. The back of the car starts doing its share rather than coasting on the fronts. Under repeated heavy stops, the larger two-piece floating discs shed rotating mass and pull heat out faster, which is what keeps a heavy G37 from going soft mid-session. Matching the pad compound to how you actually drive sharpens that further: a calmer, quieter Street setup for the daily commute, a Sport compound for fast road, or the Racing compound that resists fade when rear temperatures climb on track. The result is a G37 that brakes deeper, more squarely, and with more confidence on turn-in.

About the Hollow rear big brake kit

The kit pairs a pair of larger two-piece floating discs with uprated calipers, sized for the G37’s rear hubs. The hollow-vane rotor castings remove rotating weight and open up surface area for heat to clear between stops. It is rear-axle-specific hardware: a left and right rear caliper and disc, not a full-car set. Pad compound is chosen at order, with Street for everyday road use, Sport for fast-road driving and the odd track day, and a full Racing compound for sustained circuit work. The caliper is a hollow-body unit as standard, with an optional Hollow Racing upgrade for committed track use that loses the dust cover, is rated to 1000C and is covered by 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 shade for £150 and premium polished-forged (Titanium, Polished Gold, Polished Silver) or candy (Candy Teal, Candy Blue, Candy Red, Candy Orange) finishes for owners who want the hardware seen. Discs come drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable at checkout. The focus throughout is controlled, repeatable rear braking rather than headline figures.
