X4F 27 1.5mm Aluminium Flex Chassis XRAY 301030 - Swiss 7075 T6  [XR-301030]

X4F 27 precision flex chassis plate

This X4F 27 aluminium flex chassis comes as a 1.5mm competition plate intended for tracks with elevated traction. It provides managed flex to alter steering characteristics and cornering balance while avoiding any implication of full-size vehicle use. The slim layout and tapered lower edges reduce chassis contact with the track surface, supporting consistent corner speed on both carpet and asphalt.

Made from Swiss 7075 T6 alloy and CNC-machined to tight tolerances, the chassis prioritizes repeatable flex behaviour and durability in racing conditions. The material and finish give teams predictable response that is easy to incorporate into setup changes.

Correct installation needs the specified hardware: HUDY Spring Steel countersunk screws #913305 M3x5 (4 pcs) must be paired with 4 pcs of shims #303118-C and 4 pcs of shims #301119-C. Follow the mounting layout exactly to obtain the intended ride height and preload of the chassis plate.

Used as a tuning element, the 1.5mm flex plate helps drivers who need sharper steering and steadier corner speed on grippy tracks; install with the specified HUDY screws and shims to achieve the intended chassis behaviour.
