XYZ Racing Hollow Rear Brake Kit — Lexus GS 430 (φ 190) (2006-2011)

The GS 430’s 1.7-tonne kerb weight and the torque of its 4.3-litre 3UZ-FE V8 ask plenty of the rear axle every time this big Lexus is hauled down from a motorway cruise or the end of a long straight. The XYZ Racing Hollow Rear Brake Kit answers that with a larger, lighter rear disc and a fixed caliper sized for the S190 platform, adding the thermal headroom the standard rear setup runs short of once the stops start coming in quick succession.

This is a rear-specific upgrade for owners who use their GS 430 hard on road or the occasional track day. A two-piece floating disc with a vaned hollow core trims rotating and unsprung mass at the back axle, while the pad compound choices let you match rear bias to how you actually drive the car rather than to a one-size catalogue spec.

What this big brake kit does for your 2006-2011 Lexus GS 430

On a rear-drive saloon as heavy as the GS 430, the rear brakes do more than people credit: they settle the car on turn-in and keep the tail from going light under trail braking. Fit the XYZ Racing rear kit and the first thing you feel is consistency, the rear discs shrug off the heat that fades a tired factory setup after a handful of hard stops. The vaned hollow rotor cuts rotating mass, so the rear axle is quicker to respond, and the parking-brake drum bore is retained so the handbrake still works. Braided lines firm the pedal by removing OE hose swell. Pick the Racing pad compound and rear bite climbs for circuit use; the Sport compound widens the heat range for fast roads; Street keeps low-temperature feel and quiet, low-dust running for daily driving. Painted finishes Red, Yellow, Gold, Black and Anodized Black are included, with a Custom Color and premium options, so the hardware reads as deliberate behind an open wheel.

About the Hollow Big Brake Kit

XYZ Racing’s Hollow range is named for its rotor design: material is removed from the disc to lower weight without giving up swept area, reducing the rotating and unsprung mass each rear wheel has to control. This kit pairs that two-piece floating disc, drilled or slotted at the same price, with a fixed multi-piston caliper that clamps more evenly than the standard single-piston sliding unit, for steadier pad wear and a firmer pedal as temperatures rise. 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 offered, Street, Sport and Racing, so the kit can be set for quiet road manners or sustained track heat. The package is built around the GS 430’s rear hub and its 190mm parking-brake drum, supplied as a matched pair, so the factory handbrake function carries over unchanged. Painted calipers come in the no-cost colours through to a Custom Color in any Pantone, plus premium polished-forged Titanium, Polished Gold and Polished Silver and candy Teal, Blue, Red and Orange.

Fitment for the Lexus GS 430 (2006-2011)

This kit is cut for the S190-generation Lexus GS 430 built from 2006 to 2011, with the rear assembly sized around the car’s 190mm (φ190) parking-brake drum and supplied as a matched pair. It is a rear-axle fitment only and retains the standard handbrake mechanism. Confirm your build year before ordering, then set your pad compound, disc style and caliper colour from the options when you order.
