XYZ Racing Hollow Rear Brake Kit — Lexus GS 400 (1991-1996)

The first-generation Lexus GS 400 carries its weight like the executive saloon it is, a long-nosed, rear-driven car that loads its back axle harder under braking than its soft factory rear brakes were ever asked to handle away from the motorway. The XYZ Racing Hollow Rear Brake Kit goes straight at that problem: a rear-axle upgrade built to hold pedal feel and rear bias when a 1991-1996 GS 400 is asked to do more than cruise.

This is the rear half of the braking equation for owners keeping a thirty-year-old rear-drive Lexus alive on track days, spirited road drives, or simply restoring stopping power that has faded over the decades. A two-piece floating disc with a vaned hollow core strips rotating and unsprung mass off the back corners, and the kit is offered with a choice of pad compound, Street, Sport or Racing, so the rear axle can be matched to how hard the car actually gets driven.

What this brake kit does for your 1991-1996 Lexus GS 400

On a saloon this heavy, the rear brakes are less about outright stopping distance and more about controlling how the GS settles when you slow it down. The vaned hollow rotors cut rotating and unsprung weight at the rear, which sharpens how quickly the axle responds and lifts heat capacity over the tired original hardware, while braided lines firm the pedal by removing OE hose swell. Run the Racing pad compound and the rear holds its bite through repeated hard stops; Sport gives firmer fast-road bite with a wider heat range; Street keeps things quiet and clean for everyday driving. The payoff is a GS 400 that stays composed when you trail the brakes into a corner, rather than nosing wide or getting light at the back.

About the Hollow Rear Brake Kit

XYZ Racing builds this as a rear-specific kit rather than a one-size all-corners set, which matters on a rear-drive car where front and rear braking demands pull in different directions. The defining feature is the two-piece floating disc with a vaned hollow core, material taken out of the rotor to drop rotating mass while keeping swept area, so the rear discs shed weight and heat together. Disc faces are drilled or slotted at the same price, and the caliper is a hollow-body forged unit as standard, with an optional Hollow Racing upgrade rated to 1000C and warranted two years for hard track use. Three pad compounds are available: Street for stock-feel road use, Sport for harder fast-road work, and Racing for sustained track temperatures. Painted caliper finishes are Red, Yellow, Gold, Black and Anodized Black at no cost, with a Custom Color in any Pantone and premium polished-forged and candy options, so the setup looks deliberate behind the wheels. Each part is sized for the rear axle of the first-generation GS and supplied as a matched pair, so the kit suits owners restoring or sharpening a car the aftermarket has largely forgotten.

Fitment for the Lexus GS 400 (1991-1996)

This kit is cut for the rear axle of the Lexus GS 400 across the 1991-1996 model years, the first-generation, rear-wheel-drive GS, and supplied as a matched pair. It is a rear-position kit, so it works alongside a matching or refreshed front setup depending on how the car is built. Confirm your exact year within that span, then set your pad compound, disc style and caliper colour from the options when you order.
