XYZ Racing Hollow Rear Brake Kit — Lexus GS 400 (φ 190) (1998-2005)

The S160-generation GS 400 was built as a refined V8 grand tourer, and its factory rear brakes were specified for measured road use rather than repeated heavy stops down to a corner. The XYZ Racing Hollow Rear Brake Kit for the Lexus GS 400 ( φ 190 ) (1998-2005) swaps that rear setup for a larger two-piece floating disc and a fixed caliper sized to work with the kind of front upgrade most owners fit first.

Bolted to the back of a roughly 1700kg saloon carrying the 1UZ-FE lump over the nose, the kit exists for thermal headroom and balance front to rear: keeping the rear axle pulling its weight under braking instead of going soft after two or three hard applications. The φ 190 reference pins the kit to the GS 400’s integral parking-brake drum dimension, so the handbrake mechanism carries over without modification.

What this brake kit does for your 1998-2005 Lexus GS 400 ( φ 190 )

You feel it most where the standard rear brakes used to give up. The vaned hollow disc sheds heat faster, so pedal travel stays consistent across a sequence of stops rather than lengthening as the rear fades. The fixed caliper flexes less than the original sliding design, which sharpens the initial bite and tightens up that long, slightly numb pedal the S160 is known for, and braided lines remove the OE hose swell that softens feel. Three pad compounds let you set the rear to match how you actually drive the car: Street for quiet, low-dust road manners, Sport for firmer fast-road bite and a wider heat range, and Racing for repeated track-day abuse. And with painted finishes Red, Yellow, Gold, Black and Anodized Black included, plus a Custom Color and premium options, the hardware looks the part behind an open wheel.

About the Hollow Rear Brake Kit

The "Hollow" name refers to the vaned hollow rotor, which cuts unsprung and rotating mass while opening internal channels for heat to escape from the braking surface. Disc faces are drilled or slotted at the same price, and the two-piece floating construction lets the rotor expand and contract freely with temperature. The rear caliper is a fixed-mount design rather than a single-piston floating unit, giving more even pad loading and a firmer pedal, and it 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. The kit ships for both rear corners with a choice of three pad compounds so the rear bias can be tuned for road, fast-road or track work, and the caliper is offered in the no-cost painted colours through to a personalised Custom Color in any Pantone, plus premium polished-forged and candy finishes. Crucially for the GS 400, the assembly is engineered around the car’s φ 190 parking-brake drum, so the integral handbrake stays fully functional once the kit is installed.

Fitment for the Lexus GS 400 ( φ 190 ) (1998-2005)

This kit is cut for the S160-generation Lexus GS 400 across the 1998-2005 model span, in rear-axle fitment and supplied as a matched pair. The φ 190 designation confirms it is matched to the 190mm integral parking-brake drum used on this chassis, so the original handbrake setup is retained. Confirm your build year falls inside the 1998-2005 window before ordering, then set your pad compound, disc style and caliper colour from the options when you order.
