The Yokomo Z2-300RF4A is an aluminium rear suspension mount made for touring car chassis. It is the front-side pickup specified for the YZ-2DTMW platform and can be used as a replacement or a sturdier upgrade to the plastic factory part.
Designed to pair with the resin bush S4-300BS, this mount provides lateral control while preserving adjustable link geometry. The assembly helps keep pivot points consistent when the car is under load, aiding setup repeatability.
As a chassis-level component it locates the suspension links, mates with bulkhead mount points, and supports consistent geometry when arms or link lengths are changed. The aluminium material increases wear resistance and maintains accurate dimensions better than stock plastic.
Select this mount when you want a firmer front-side rear pickup that teams with the S4-300BS resin bush to protect geometry through setup and track use.
