Caliper render for this kit:
The Lexus GS 400’s 1UZ-FE V8 sits well forward in the S160 saloon’s nose, and the car’s standard front braking specification was tuned to the luxury brief that defined the platform, progressive, quiet, and adequate for road use rather than repeated hard stops. Ask the stock setup to manage those loads consistently and the limitations of that brief become apparent quickly.
This XYZ Racing Hollow front brake kit targets the GS 400’s front axle directly as a matched pair of front calipers and two-piece floating discs, with three pad compounds, Street, Sport, and Racing, letting the hardware suit the car’s actual use. A GS 400 pressed hard on a fast B-road needs different friction characteristics from one that arrives at a circuit, and the compound choice addresses both.
What this brake kit does for your 1998-2005 Lexus GS 400
The V8’s nose-heavy layout means the S160’s front axle carries the dominant share of braking load under hard deceleration, making the front end the logical place to concentrate the upgrade. Fitting the Hollow kit here reduces the heat build-up that compromises the standard setup when stops come repeatedly, a characteristic that matters more in the GS 400 than in lighter, smaller-engined cars on the same platform, while the hollow-vane disc sheds heat through the rotor body. Street is the quiet, low-dust default; Sport suits the saloon’s primary fast-road role with improved bite and temperature tolerance; Racing is for owners who want the braking to hold up through extended circuit sessions. Caliper colour is included in Red, Yellow, Gold, Black, or Anodized Black at no extra cost, enough range to remain understated or make a deliberate statement behind the GS 400’s wheels. Custom Color matches any Pantone for £150, with 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 kit takes its name from its hollow-vane disc construction, a design intended for drivers who want more from their braking hardware than the stock fitment delivers. 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 high-load track conditions, no dust cover, rated to 1000C, two-year warranty. Three pad grades are offered from the outset: Street for everyday road use, Sport for improved bite and temperature tolerance over stock, and Racing for circuit fade resistance. Caliper colour is included across Red, Yellow, Gold, Black, and Anodized Black, with a Custom Color route and premium finishes alongside, giving the flexibility to integrate the kit into a considered build or to treat the braking upgrade as a visual element in its own right. Discs come drilled or slotted at the same price, with two-tone anodized centre bells in five colours or titanium selectable at checkout. The front-only fitment reflects where the GS 400’s V8 layout concentrates the braking demand.
Fitment for the Lexus GS 400 (1998-2005)
Confirmed fitment for the Lexus GS 400 across the 1998 to 2005 span, covering the S160-platform four-door saloon. As with any kit that increases caliper dimensions over the OEM specification, clearance against the inner face of the wheel should be verified before installation, particularly where aftermarket wheels with different offset or barrel geometry are fitted.

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.
