XYZ Racing Hollow Front Brake Kit — Lexus GS 300 JZS147 (1991-1996)

The JZS147 sits in an interesting position in the Lexus catalogue: a 2JZ-powered rear-wheel-drive saloon launched before the brand had fully established its sporting credentials, yet heavy enough at the kerb to make repeated hard braking a genuine test of its factory front brakes. These cars are now thirty-plus years old, and the owners who still drive them hard, whether on fast roads or occasional track days, want hardware that keeps pace with what the 2JZ platform can produce.

This XYZ Racing Hollow Front Brake Kit addresses the front axle directly as a matched pair of front calipers and two-piece floating discs. Three pad compounds, Street, Sport, and Racing, mean a single kit specification can be matched to how the JZS147 is actually used, from daily road miles to more committed driving.

What this brake kit does for your 1991-1996 Lexus GS 300 JZS147

On a saloon of the JZS147’s mass, the front brakes handle the majority of deceleration force under hard application. The hollow-vane disc lowers rotating and unsprung mass at each front corner, sharpening steering feel through the braking phase where the standard cast discs would add inertia. Thermal dissipation improves with the hollow design, heat leaving the rotor body faster and keeping pad temperature more consistent across a series of hard stops. Compound choice matters on a car of this weight: Street is the quiet, low-dust default with progressive cold-morning bite; Sport widens the heat range for harder road work; Racing extends the working temperature window for track applications where sustained heat build-up becomes a real factor. Caliper colour is included in Red, Yellow, Gold, Black, or Anodized Black at no extra cost, with Custom Color matching any Pantone for £150, plus premium polished-forged finishes in Titanium, Polished Gold, and Polished Silver, and candy finishes in Teal, Blue, Red, and Orange.

About the Hollow brake kit

The Hollow brake kit is built around a disc design that removes material strategically from the rotor body, reducing mass without sacrificing the structural section needed for high-load stops. The hollow-vane geometry channels heat away from the pad interface more aggressively than a solid equivalent, targeting the fade window that affects heavier GT platforms under sustained braking. The two-piece floating disc lets the rotor expand cleanly under heat, and braided lines keep the pedal firm. The caliper is hollow-bodied as standard, with a Hollow Racing upgrade for higher-temperature motorsport use, no dust cover, rated to 1000C, two-year warranty. Three compound grades, Street, Sport, and Racing, are available at point of order, covering direct-replacement road use through to the circuit. Caliper colour runs to Red, Yellow, Gold, Black, and Anodized Black at no upcharge, with Custom Color and premium finishes alongside. Discs come drilled or slotted at the same price, with two-tone anodized centre bells in five colours or titanium selectable at checkout.

Fitment for the Lexus GS 300 JZS147 (1991-1996)

This kit is built for the Lexus GS 300 on the JZS147 platform, covering the full first-generation run from 1991 to 1996. The JZS147 carried the 2JZ inline-six with rear-wheel drive throughout its life, and this front brake kit is matched to that platform’s geometry and hub specification. If the front brake system has been previously modified, verify the original factory specification applies before fitting.
