Caliper render for this kit:

The XU30-generation RX 330 hides close to two tonnes behind its soft, comfort-first ride, and almost all of that mass pitches forward the moment you brake. The rear axle on this Lexus does relatively little work in normal driving, which is exactly why it gets neglected, and exactly why it starts to matter once the car is loaded with passengers, luggage or a trailer.
The XYZ Racing Hollow Rear Brake Kit for the Lexus RX 330 (XU30) sets out to correct that imbalance. Its two-piece floating discs cut rotating and unsprung mass at the back axle while adding thermal headroom, so the rear brakes keep contributing after the fronts are heat-soaked on a long alpine descent or a heavy motorway haul.
What this brake kit does for your 2003-2008 Lexus RX 330 (XU30)
On a heavy, front-biased SUV the first thing you feel is a firmer, more consistent pedal under repeated stops, the kind a loaded RX 330 demands coming down a mountain pass or pulling a caravan. The two-piece floating disc dumps heat faster than a solid OE-style rotor, so fade arrives later and the pedal stays where you left it. Pad compound is your call: the Street compound keeps daily refinement and low dust, the Sport pad steps up bite and heat range for harder driving, while the Racing compound brings the most aggressive friction for owners who tow at weight or drive the car hard. Painted caliper finishes in Red, Yellow, Gold, Black or Anodized Black, with premium and Custom Color routes besides, tidy up the view behind the wheel at the same time.
About the Hollow Rear Brake Kit
The defining feature is the two-piece floating rotor, lighter than a conventional solid disc of the same size. Less rotating mass means the brakes spin up and slow down with less inertia, and the internal vane structure gives the disc more capacity to take on and shed heat, the two things that govern fade on a vehicle as heavy as the RX 330. This is a rear-axle kit, supplied as a pair and sized to the XU30’s rear hub and caliper geometry rather than a generic bracket. The caliper is hollow-bodied as standard, with an optional Hollow Racing caliper for harder use that removes the dust cover, is rated to 1000C and carries a two-year warranty. Three pad compounds are offered, Street, Sport and Racing, so the kit can be specced for quiet daily use or for genuine thermal load. Caliper finishes run to painted Red, Yellow, Gold, Black and Anodized Black at no cost, with premium polished-forged Titanium, Polished Gold and Polished Silver, candy Teal, Blue, Red and Orange, or a Custom Color in any Pantone for £150, painted to hold up behind an open wheel. Discs are drilled or slotted at the same price, with two-tone anodized or titanium centre bells available at checkout.
Fitment for the Lexus RX 330 (XU30) (2003-2008)
This kit is built for the XU30-chassis Lexus RX 330 across the 2003 to 2008 model years, fitting the rear axle as a pair. The XU30 covers the second-generation RX, and the kit is matched to that platform’s rear hub and caliper mounting. Confirm your build year falls inside the 2003-2008 span 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 330–356mm (rear). 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.
