This aluminum rear suspension mount is an optional RC-scale part for the 4WD off-road YZ-4 platform, designed for the L5 suspension arm. The rear-side suspension pin spacing on this mount is 2mm narrower than the standard rear mount, a dimensional change intended to alter rear-end geometry without modifying the arm itself.
When paired as a set with the front-side rear suspension mount Z4-300LRF and used together with the 1mm longer L5 suspension arm Z4-008RS5, the assembly allows adjustment of the car's overall track width while keeping the longer arm length. On high-grip surfaces such as carpet or artificial turf, this mount helps induce a moderate amount of chassis roll even when the suspension is set stiffer, which can improve turning performance without fundamentally changing handling character.
To address front-to-rear balance, the mount can be used alongside a 1mm longer front suspension arm Z4-008F1 for further tuning of weight transfer and turn-in behavior. This description refers solely to RC-scale setup and parts.
