XYZ Racing Hollow Rear Brake Kit — Luxgen S3 (2016-2026)

The Luxgen S3 carries its braking load up front, the way every front-drive compact saloon does, and that leaves the rear axle doing quiet, undervalued work that gets exposed the moment you start stopping hard and often. This XYZ Racing Hollow Rear Brake Kit for the Luxgen S3 addresses that imbalance directly, giving the back axle a larger, better-cooled disc that keeps the car settled under heavy retardation rather than letting the front do everything until it overheats.

It is a rear-specific upgrade, designed to pair with a sharper front setup or simply to firm up the standard car’s stopping behaviour. The two-piece floating disc sheds heat and weight, which matters more than people assume on a light Taiwanese saloon where unsprung mass at the rear influences how composed the chassis feels mid-corner.

What this brake kit does for your 2016-2026 Luxgen S3

After fitting, the first thing you notice is a firmer, more progressive pedal under repeated stops, the kind of consistency the standard rear setup loses once it gets warm. The larger rear disc and floating-vane construction pull heat out faster, so brake balance stays where the chassis wants it instead of drifting forward as the rear fades. On a front-heavy S3 that translates into less nose-dive twitchiness and a more stable platform when you brake into a roundabout or trail the pedal towards an apex. Pad compound is your lever here: the Street option keeps things quiet and low-dust for daily driving, Sport steps up bite and heat range for harder use, while the Racing compound holds bite through sustained track and fast-road work. The result is a rear axle that contributes properly rather than coasting along behind an overworked front end.

About the Hollow rear brake kit

This is a bolt-on rear big brake kit built around a two-piece floating disc, where the internal vane structure cuts rotational and unsprung weight while increasing the surface area that carries heat away from the friction face. The caliper is hollow-bodied as standard, with an optional Hollow Racing caliper for harder use that drops the dust cover, is rated to 1000C and carries a two-year warranty. The kit ships with a choice of three pad compounds, Street, Sport and Racing, so the same hardware suits a road-biased S3 or one that sees occasional track and fast-road work. Calipers are painted in Red, Yellow, Gold, Black or Anodized Black at no extra 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, letting you match or contrast the wheel and bodywork. Discs are drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable at checkout. The engineering priority is thermal management and consistent torque delivery at the rear, the area most road cars neglect, rather than headline disc diameter alone. Everything is sized specifically for the S3’s rear hub geometry, supplied as a pair, so it works with the existing handbrake and parking provision.

Fitment for the Luxgen S3 (2016-2026)

This kit is configured for the Luxgen S3 across the 2016 to 2026 model span and fits the rear axle only, as a pair. Confirm your build year and current rear brake specification against the options above before ordering, then choose your pad compound and caliper colour to suit how the car is used.
