XYZ Racing Hollow Rear Brake Kit — Lexus LS 350 (XF50) (OE190) (2018-2026)

The fifth-generation LS rides on Toyota’s GA-L architecture and carries the mass of the full-size flagship it is, which means a genuine thermal load passes through the rear axle every time you scrub speed off a motorway cruise. The XYZ Racing Hollow Rear Brake Kit for the Lexus LS 350 (XF50) (OE190) meets that head on, replacing the standard rear setup with a lighter two-piece floating disc built to shed heat faster and keep the pedal firm when the factory brakes would start to go soft.

This is the rear half of the braking equation on a heavy, rear-drive luxury saloon, where stability under hard deceleration leans on the back axle as much as the front. With pad compounds running from Street to full Racing, and a disc that trims rotating and unsprung mass, it turns the LS 350’s relaxed cruiser brakes into hardware that copes with repeated, deliberate stops rather than one big one.

What this brake kit does for your 2018-2026 Lexus LS 350 (XF50) (OE190)

The lighter two-piece disc cuts rotating mass at the rear corners, so the LS feels a touch more willing to respond and the brakes warm into their working range sooner. More importantly, the extra heat capacity keeps bite consistent through a long descent or a sequence of high-speed stops, where the OE rear discs on a two-tonne saloon tend to fade. The pad-compound choice lets you set the rear bite to match how you drive, from quiet daily use on the Street compound, through the added bite and heat range of the Sport pad, to a Racing pad that holds up under sustained load. The painted caliper finishes mean the upgrade reads through the wheels as cleanly as it performs.

About the Hollow rear brake kit

The kit is built around a two-piece floating rear disc, where the internal vane structure drops weight and opens up cooling paths without sacrificing the swept area you need to manage heat on a heavy car. It pairs that rotor with an uprated rear caliper, hollow-bodied as standard, for stronger, more even clamping than the OE sliding setup. Track-focused owners can specify the Hollow Racing caliper, which 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 same hardware serves a comfortable road LS or a car driven hard on a private circuit. Calipers come painted in Red, Yellow, Gold, Black or 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, and centre bells can be upgraded to two-tone anodized in five colours or titanium at checkout. The whole package is engineered to raise the rear axle’s thermal ceiling on the XF50, the area a stock luxury saloon brake is least prepared for once you start using the performance the chassis has.
