Caliper render for this kit:
The 1UZ-FE’s effortless torque makes the SC 400 a genuinely rapid car on a fast B-road, but at around 1,700kg, repeated heavy braking from high speed asks more of the factory front calipers than they were designed to deliver. The Z30’s braking was specced for refined deceleration, not sustained hard stops, and that limitation becomes apparent on a track day or a committed cross-country run where pedal confidence erodes as heat builds.
The XYZ Racing front big brake kit for the SC 400 addresses the front axle directly, where the V8’s engine mass concentrates deceleration load. It is a single-axle upgrade: a matched left-and-right pair of front calipers and two-piece floating discs with braided lines. Three pad compounds, Street, Sport and Racing, plus a choice of painted caliper colours, let owners match the upgrade to exactly how the car is used.
What this brake kit does for your 1991-2000 Lexus SC 400
Front braking carries a disproportionate share of the work on any front-heavy GT, and the SC 400’s 1UZ-FE sits well ahead of the axle centreline. That weight distribution means under hard deceleration the front calipers work hardest at exactly the point where heat accumulation is worst. The two-piece floating disc’s hollow-vane friction ring manages that thermal load, moving heat away from the rotor face and reducing the surface saturation that translates into a lengthening pedal and reduced feel. Selecting the Sport or Racing pad tightens initial bite and maintains progression through hard successive stops rather than fading back after the third, while Street keeps things quiet and low-dust. Painted caliper colours, Red, Yellow, Gold, Black or Anodized Black at no extra cost, mean the upgrade is visible through the SC 400’s alloys, and the confidence it adds becomes apparent the first time you carry real speed into a corner and use the brakes fully.
About the front big brake kit
The XYZ Racing front big brake kit is a direct-replacement front-axle upgrade built around two-piece floating discs that improve thermal dissipation compared to solid equivalents. Heat is the enemy of repeated hard braking, and the hollow-vane friction ring increases internal airflow across the rotor, reducing the temperature build-up that undermines pedal feel and pad consistency. The caliper is a hollow-body forged unit as standard; for the hardest sustained use you can step up to the Hollow Racing caliper, which loses the dust cover, is rated to 1000C and carries a two-year warranty. Painted caliper colours are Red, Yellow, Gold, Black and Anodized Black, with any Pantone available as a Custom Color for £150, premium polished-forged finishes in Titanium, Polished Gold and Polished Silver, and candy finishes in Teal, Blue, Red and Orange. The pad selection spans Street all-weather specification, an uprated Sport compound for spirited fast-road driving, and a full Racing compound for circuit events, each tuned to a different heat window and friction characteristic. Discs come drilled or slotted at the same price, with a centre-bell upgrade to a two-tone anodized finish in five colours or to titanium at checkout.
Fitment for the Lexus SC 400 (1991-2000)
This front brake kit is listed against the Lexus SC 400 (Z30 platform), covering the full 1991 to 2000 production run, and fits the front axle as a left-and-right pair. The Z30 SC 400 was sold alongside the Toyota Soarer UZ-FE in some markets, sharing the base platform; this kit is specified for the Lexus-badged SC 400 variant. Confirm your chassis code and verify that no previous owner has fitted non-standard front suspension geometry before ordering.

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.
