Caliper render for this kit:

The RC 300 sits below the RC F in Lexus’s coupe range, but the GS-derived platform’s kerb weight and the factory brake specification, callipers sized for refined road use rather than sustained hard stops, mean the front-axle hardware does not fully match the car’s mass once you start pushing the pace. A track session, a long descent or repeated hard braking on the road exposes that gap clearly.
The XYZ Racing front big brake kit for the 2014-2017 RC 300 closes it. It is a single-axle upgrade: a matched left-and-right pair of front calipers and two-piece floating discs with braided lines. The two-piece floating disc reduces rotating mass at the front wheels and improves heat dissipation through better airflow, while three pad compounds, Street, Sport and Racing, mean the kit configures for daily driving or track use from the same hardware.
What this brake kit does for your 2014-2017 Lexus RC 300
The front axle on a front-engined RWD coupe of the RC 300’s weight class handles a significant proportion of braking force under any meaningful deceleration, which is why the two-piece disc’s reduced rotational inertia matters here: less mass spinning at each corner means the front suspension reacts more accurately over braking bumps and heat accumulates less aggressively through repeat stops. The hollow-vane friction ring carries that heat off the disc face. The three pad compounds address the RC 300’s split personality: Street covers quiet, low-dust road performance without compromising daily comfort, Sport improves fade resistance for drivers who use the car hard on the road, and Racing holds up through sustained on-track braking cycles where Sport-spec pads would soften. Painted caliper colours, Red, Yellow, Gold, Black or Anodized Black at no extra cost, let the front brakes complement or contrast with the RC’s factory wheel finish without a paint job.
About the front big brake kit
The two-piece floating disc is the key engineering distinction. Conventional cast discs move air radially through internal vane channels; the hollow-vane friction ring sheds material more aggressively, reducing both rotational inertia and the thermal mass that stores heat during repeat braking. The result is a front assembly that builds temperature more slowly and recovers faster between stops, relevant on any front-engined car carrying the RC 300’s build quality and weight. The caliper is a hollow-body forged unit as standard; for sustained track work you can step up to the Hollow Racing caliper, which loses the dust cover, is rated to 1000C and carries a two-year warranty. The three compound grades are distinct specifications, not one compound rebranded: Racing needs working temperature to perform at its best but resists the fade that pushes the Sport compound past its effective range at sustained pace. 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. 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 RC 300 (2014-2017)
This front brake kit is built specifically for the Lexus RC 300 produced between 2014 and 2017 and fits the front axle as a left-and-right pair. The XYZ-BRK-BKF-LE-026-FRONT part reference covers the front assembly for this fitment. If the car has had prior brake modifications, confirm the existing front rotor specification 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.
