Project 4X Extra Flex Chassis Plate Arrowmax AM-900008  [AM-900008]

Arrowspace Mg extra-flex centre plate for Project 4X setups

The Arrowmax AM-900008 Arrowspace Mg Extra Flex plate is an aftermarket chassis hop-up created to alter flex characteristics on Serpent Project 4X cars. It supplies an alternate stiffness profile so tuners can refine handling without changing primary suspension or drivetrain components.

Fitment and role: the component replaces the central chassis plate or brace to modify the flex envelope. Choosing a magnesium extra-flex plate influences mid-corner compliance and steering feedback by changing how loads move through suspension pick-up points. The part suits systematic tuning where incremental changes are tested.

Installation notes: installation calls for basic removal of the chassis centre section and reuse of the original fixings; standard hand tools used for Project 4X maintenance are sufficient. Confirm alignment and positive thread engagement on reassembly and ensure clearance to the motor, ESC and servo. No drivetrain modifications are required.

Tuning guidance: use the plate as one variable within a full setup process. Pair it with shock, spring and tyre changes, logging each adjustment. Expect measured handling refinements rather than dramatic leaps, useful for circuit-side trimming and balance work.
