Fits Lexus RX 450h (AL10) (2008-2015)

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 Rear Brake Kit — Lexus RX 450h (AL10) (2008-2015) — 380 mm
380 mm

The third-generation Lexus RX 450h on the AL10 chassis is a heavy hybrid, well over two tonnes once it is loaded, and its rear axle does more braking work than the comfort-tuned pedal ever lets on. This XYZ Racing Hollow Rear Brake Kit for the Lexus RX 450h (AL10) replaces the standard rear hardware with a lighter, better-cooled package built to stay consistent when the regenerative system tapers off and the friction brakes take the load.

On a hybrid this size, the brakes that earn their keep are the ones working hard on long descents and when the drive battery is full and regen backs away. The two-piece floating disc sheds rotating mass and pulls heat out faster, so the rear end keeps its bite on repeat stops instead of going soft halfway down a mountain pass.

What this brake kit does for your 2008-2015 Lexus RX 450h

Fit this kit and the most obvious change in a 2008-2015 Lexus RX 450h is pedal consistency under weight. The two-piece floating disc lowers rotating and unsprung mass at the rear axle, which sharpens initial response and helps the discs dump heat on sustained descents, exactly where a two-tonne hybrid crossover punishes its brakes. Three pad compounds let you match the kit to how you actually drive: Street for quiet daily commuting and low dust, Sport for firmer bite and more heat range when the RX is loaded or towing, and Racing for the most aggressive friction if you lean on it hard. Painted caliper colour options in Red, Yellow, Gold, Black or Anodized Black, with premium and Custom Color routes besides, let the rear hardware sit cleanly behind the factory or aftermarket wheels.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit is XYZ Racing’s rear-axle upgrade built around a two-piece floating disc that trades dead weight for airflow. Removing material from the rotor cuts rotating mass without giving up swept area, and the internal venting clears heat faster than a solid equivalent, the two factors that decide whether a heavy vehicle’s brakes fade after repeated stops. The kit pairs those discs with position-specific calipers, hollow-bodied as standard, and a choice of three pad compounds: a low-dust Street pad, a firmer Sport compound for fast road and occasional track, and a full Racing friction material for harder use. Owners chasing serious track durability can step up to the Hollow Racing caliper, which removes the dust cover, is rated to 1000C and carries a two-year warranty. Because it is a rear-specific kit, supplied as a pair, it is set up to rebalance braking effort toward the back axle, which a nose-heavy hybrid like the RX 450h tends to under-use. Caliper finishes run 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. 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 450h (RX 450h (AL10)) (2008-2015)

This kit is built specifically for the third-generation Lexus RX 450h on the AL10 chassis, covering the 2008 to 2015 model years. It fits the rear axle as a pair and is matched to the RX 450h’s hybrid running gear. Confirm your exact build year within the AL10 range before ordering, then choose your pad compound and caliper colour to suit how the car is used.

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.
