Fits Lexus GS 430 (1993-2004)

Brake pad compound

Street: quiet, low-dust, strong cold bite for road driving. Sport: higher temperature range and more bite for fast road and occasional track. Racing: maximum fade resistance for sustained track use (noisier and dustier cold). Match the pad to how hard you actually brake.

Disc size

Caliper grade

Hollow is the standard caliper: a lighter hollow-body forged caliper with a dust cover and a 5-year warranty. Hollow Racing drops the dust cover for sustained high-temperature use (rated to 1000°C, 2-year warranty) — the track-grade choice.

Caliper colour

Painted colours are included. Polished-forged finishes are mirror-polished forged calipers (Titanium, Gold, Silver); candy colours are a deep, mirror-reflection paint. Both are premium upgrades — fuller detail further down the page.

Disc style

Drilled discs (cross-drilled holes) vent gas and water and look aggressive; slotted discs (surface grooves) wipe the pad face clean and resist fade under sustained hard use. Same price — choose on looks or how you drive.

Centre bell

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. Standard anodized is included; a two-tone bell adds an anodized accent ring in your choice of colour; titanium is the lightest, forged option.

Carbon-ceramic rotor

Carbon-ceramic rotors are a special-order track upgrade: far lighter than steel, fade-resistant at extreme temperatures and extremely long-lived. The price follows the disc size you choose above. The standard two-piece steel rotor is included.

XYZ Racing Hollow Front Brake Kit — Lexus GS 430 (1993-2004) — 330 mm
330 mm

The Lexus GS 430’s 4.3-litre V8 and the substantial mass of the S160’s all-steel body make a combination that will eventually expose the limits of the factory front brake specification, a fact most GS 430 owners meet on a long descent or the first time the car is used somewhere brakes are cycled repeatedly rather than in isolation. The XYZ Racing Hollow Front Brake Kit replaces the OEM front anchors with hardware designed to manage sustained thermal load, not merely occasional hard stops. It is supplied as a matched pair of front calipers and two-piece floating discs.

Where the GS 430’s chassis was always quietly capable, more dynamically able than its GT-car brief implied, the standard brakes were calibrated for the comfort-biased majority of its original buyers. This kit resets that balance for owners who use the car as it can be used.

What this brake kit does for your 1993-2004 Lexus GS 430

The GS 430’s front-engine, rear-drive layout means braking weight transfer loads the front axle heavily; the front brakes carry the lion’s share of deceleration work, and it is the front end that shows fade first when the thermal budget is exceeded. Hollow-vane disc construction reduces disc mass compared to the OEM items, which lowers the heat energy that needs managing and improves dissipation through the rotor body during repeated hard use. Three pad compounds match the system to the car’s environment: Street is the quiet, low-dust default for predominantly road use, Sport for mixed driving with occasional hard sessions, Racing for track days where temperatures run higher and fade resistance becomes the priority throughout a session. 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 Front Brake Kit

The hollow-vane disc is the central departure from the GS 430’s factory specification. By engineering air channels into the disc body, the design reduces overall rotating mass without sacrificing swept area or structural rigidity, less unsprung weight at the front axle, and a disc that moves heat through its body more effectively under sustained load. 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 circuit work, no dust cover, rated to 1000C, two-year warranty. Caliper finish is included across Red, Yellow, Gold, Black, and Anodized Black, with Custom Color and premium finishes alongside, making the install a considered choice given the GS 430’s clean five-spoke wheel openings that leave little hidden. Discs come drilled or slotted at the same price, with two-tone anodized centre bells in five colours or titanium selectable at checkout. Compound selection across three grades covers daily commuting through to circuit work without a hardware change between sessions.

Fitment for the Lexus GS 430 (1993-2004)

This kit is listed for the Lexus GS 430 across the 1993-2004 span, covering both the first-generation Z30 platform (1993-1997) and the second-generation S160 (1998 onwards). The two generations use different front suspension geometry, so confirm your chassis code and specific variant with the supplier before ordering; disc hat dimensions and caliper bracket clearances differ between platforms, and getting this right before the parts arrive avoids a return shipment.

Choosing your spec

Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.

Brake pads — Street, Sport or Racing

Every kit ships with a full set of high-performance pads; the compound is your call.

Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.

Caliper grade — Hollow vs Hollow Racing

Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.

Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 286–380mm (front). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.

Caliper colour & finish

Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).

Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.

Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).

Centre bells

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
