XYZ Racing Hollow Rear Brake Kit — Lexus NX (AZ20) (2021-2026)

The second-generation NX (AZ20) is a heavy thing to slow down. In 450h+ plug-in form it crowds 2.1 tonnes, and the rear axle carries battery mass that the factory brakes were sized to manage on a spec sheet rather than on a long Alpine descent with a full cabin. This XYZ Racing Hollow rear brake kit for the Lexus NX (AZ20) goes straight at that thermal ceiling, adding rotating area and a stiffer caliper where the standard setup runs out of headroom.

On a TNGA-K crossover the rear brakes spend most of their working life shadowed by regenerative braking, which quietly masks pad glaze and uneven disc wear until the moment you actually need mechanical friction. A larger, lighter two-piece floating disc restores honest pedal feedback and gives the back axle the bite to help settle the NX under trail-braking, instead of asking the fronts to carry everything.

What this brake kit does for your 2021-2026 Lexus NX (AZ20)

The two-piece floating disc trims rotating and unsprung mass at each rear corner, which sharpens turn-in slightly and calms wheel hop over broken B-road surfaces, useful on a tall, softly damped SUV. You feel it most as fade resistance: repeated heavy stops on a motorway run or a loaded descent no longer push the pedal long. Three pad compounds, Street, Sport and Racing, let you match bite and dust levels to how you actually use the car, from quiet commuting on the Street pad, through the firmer Sport compound for spirited weekend driving, to a Racing compound for sustained track heat. And because the caliper ships painted in Red, Yellow, Gold, Black or Anodized Black, with premium and Custom Color routes besides, the upgrade reads behind the wheel spokes rather than hiding.

About the Hollow Rear Brake Kit

The Hollow rear brake kit pairs an enlarged two-piece floating disc with a multi-piston fixed caliper that clamps more evenly than the sliding-pin rear arrangement it replaces. The disc is the centre of the design: internal venting and a lightened structure shed weight while increasing the surface area available to dump heat, so the assembly recovers faster between stops. Caliper rigidity is the other half of the story; the hollow-bodied caliper keeps the pad square to the disc under load, which is what gives you a firm, repeatable pedal rather than a long, mushy one once temperatures climb. Track-focused owners can step up to the optional Hollow Racing caliper, which drops the dust cover, is rated to 1000C and carries a two-year warranty. The three compound options span Street, Sport and a Racing friction material, so the same hardware suits a daily NX or a heavily driven one. Calipers come 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. Discs are drilled or slotted at the same price, with two-tone anodized or titanium centre bells available at checkout.
