This front knuckle is a CNC aluminium replacement for the Kyosho Optima 2016 chassis, intended to replace the standard plastic part with a stiffer steering mounting solution and more consistent geometry under load. The content concentrates on fit, installation guidance, and the tuning role of the component rather than making direct performance claims.
Installation notes: the knuckle secures to the original steering upright and suspension tower anchor points on the Optima 2016 and matches the factory bore positions. Verify steering linkage clearances and thread compatibility for hex screws and ball studs before final assembly. Remove the stock component carefully, position the new knuckle on the upright, and fasten using the original mounting hardware or equivalent fasteners matching the thread and length.
Tuning role: replacing the plastic knuckle with aluminium reduces local compliance at the steering pivot, changing steering feedback and response to bumps. Use this part when adjusting toe, camber link settings, or shock valving to fine tune steering characteristics without modifying the base chassis geometry.
