XYZ Racing Hollow Rear Brake Kit — Lexus GS 300 JZS147 (φ 190) (1991-1996)

The JZS147 GS 300 left the factory as a quiet 2JZ-powered cruiser, and its rear brakes were specified to match: enough to settle a heavy, Giugiaro-styled saloon back from a motorway cruise, not to absorb repeated hard stops. Once these cars get used the way owners actually use them now, on spirited B-road runs, drift practice, the occasional track day, the standard rear setup is the first thing to fade. This XYZ Racing Hollow Rear Brake Kit for the Lexus GS 300 JZS147 (1991-1996) addresses exactly that shortfall.

It is a direct-fit rear upgrade built around a lightweight two-piece floating disc and a fixed caliper, sized to the φ190 rear hub specification this chassis uses. The aim is a firmer, more consistent rear bite that lets you balance a car carrying real mass over the back axle.

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

On a kerb-weight saloon like the GS 300, rear braking does more work than most owners credit, and a stronger rear end steadies the car under trail-braking instead of letting the nose dive and the tail go light. You feel it as a more planted, predictable stop and a pedal that stays consistent when you brake hard, repeatedly. The vaned hollow rotor sheds rotating and unsprung mass at the hub, which sharpens response and helps the discs shed heat between corners, and braided lines firm the pedal by removing OE hose swell. Three pad compounds let you set the kit up for how you drive: Street for quiet, low-dust daily use, Sport for firmer bite and a wider heat range on fast roads, and Racing for sustained high-temperature track work. The fixed caliper keeps pad contact even as the disc heats.

About the rear big brake kit

The kit pairs a multi-piston fixed caliper with a two-piece floating disc, replacing the factory rear assembly as a complete bolt-on package supplied for both rear corners. The vaned hollow core cuts unsprung and rotating weight while preserving thermal capacity, so the discs come up to temperature quickly and stay stable under load. Disc faces are drilled or slotted at the same price. 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. Pad choice is the kit’s main tuning lever: Street suits road use, Sport steps up cold bite and heat range, and Racing targets sustained high-temperature work. 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 visible hardware behind the wheel matches the rest of the build. Everything is matched to the GS 300’s φ190 rear specification, which keeps the parking-brake function and rear geometry intact.
