This aluminium rear lower suspension mount is supplied as a replacement for the Kyosho FW05-R low-position lower mount. Machined for greater rigidity than the standard plastic part, it provides a firmer anchor for rear suspension elements on road-focused builds.
Fitment is restricted to FW05-R labelled chassis types; confirm your chassis code before ordering. The component is structural and will influence the rear roll centre and how the rear arm handles corner loads when used with existing hubs and arms.
Installation is a simple swap for experienced modellers: remove the factory lower mount, trial-fit the aluminium unit on the existing bosses and secure with the original hardware. After fitting check travel and clearance to avoid binding, and reassess ride height and toe after a short run.
In tuning terms, an aluminium lower mount reduces compliance and firms up rear response, altering mid-corner behaviour and steering transient feel. Adjust suspension and front-end settings in small increments to find the desired balance.
