The Yokomo Z2-300RF4A is an aluminium rear suspension mount for RC touring car chassis, acting as the front-side mounting point on the YZ-2DTMW platform. It is suitable as a replacement part or an upgrade where enhanced stability is desired.
This mount is intended to be used with the resin bush S4-300BS to provide lateral support while allowing for adjustable suspension geometry. The pair keeps pivot locations consistent under load and supports precise toe and camber adjustments during setup.
In practice the part locates suspension links, interfaces with the bulkhead mount points, and promotes repeatable geometry when arms or link lengths are changed. Aluminium construction brings better dimensional stability and wear resistance compared with the original plastic components.
Opt for this mount when consistent front-side rear geometry is a priority and you plan to use the S4-300BS bush to maintain alignment during setup changes.
