XYZ Racing Hollow Rear Brake Kit — Lexus RX (AL20) (2015-2026)

The Lexus RX (AL20) is a near two-tonne luxury crossover that asks a lot of its brakes every time you scrub speed off a motorway cruise or hold a long downhill grade. Its mass sits high and forward, which leaves the rear axle doing quiet but important work keeping the car balanced and stable under heavy braking. The XYZ Racing Hollow Rear Brake Kit upgrades that rear corner with larger, two-piece floating discs and an uprated caliper, restoring bite and consistency where the standard setup starts to wilt.

This is a rear-axle kit, so it is about brake balance and fade resistance more than headline stopping power on its own. On a heavy RX used for towing, family loads or quick A-road work, that means a firmer pedal that holds its travel after repeated stops, and a rear end that stays composed when you lean on the brakes.

What this brake kit does for your 2015-2026 Lexus RX (AL20)

Fit this kit and the first thing you notice is pedal feel: a stiffer caliper flexes far less than the standard unit, so the bite point arrives sooner and stays put. The two-piece floating disc sheds heat faster and trims rotational mass at the rear axle, which helps an RX this heavy recover between stops instead of cooking its pads on a long descent. Pad compound is yours to pick: the Street option keeps things quiet and low-dust for daily use, Sport steps up bite and heat range for harder driving, and the Racing compound is there if you load the car for track days or steep descents with a trailer. Painted caliper colour runs from understated Black through Red, Yellow, Gold and Anodized Black, with premium and Custom Color routes besides, so the upgrade reads as deliberate behind the RX’s larger wheels.

About the Hollow Big Brake Kit

XYZ Racing builds this kit around larger discs and calipers than the Lexus RX (AL20) carries from the factory, giving the rear axle a meaningful step up in clamping area. The two-piece floating disc is the defining detail: removing material from the disc trims weight without giving up thermal capacity, lowering both unsprung and rotational mass at the rear. The caliper is hollow-bodied as standard, with an optional Hollow Racing caliper for serious track use that drops the dust cover, is rated to 1000C and carries a two-year warranty. Three pad compounds, Street, Sport and Racing, let you match the kit to how the car is actually used, from quiet commuting to repeated heavy braking under load. The caliper is painted in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with premium polished-forged Titanium, Polished Gold and Polished Silver, candy Teal, Blue, Red and Orange, or a Custom Color in any Pantone for £150, so it suits anything from a factory-look sleeper to a show-spec build. Discs are drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable at checkout. Because it is a rear-specific kit, supplied as a pair, the components are sized to the RX rear hub and disc geometry rather than carried over from another platform.
