Kyosho FW05-R Rear Low Mount Performance Upgrade FW05-002 by 3Racing  [FW05-002]

Low-position rear lower mount - race setup

This aluminium rear lower suspension mount is a precision upgrade intended for Kyosho FW05-R chassis running low rear arm geometry. Machined for improved stiffness over the OEM plastic part, it provides a stiffer mounting point to reduce compliance and support consistent handling at higher cornering loads.

Compatibility is limited to FW05-R designated chassis variants; verify your chassis code before ordering. The mount is a structural component that shifts rear roll centre characteristics and changes how the rear arm transmits load to the hub under dynamic cornering conditions.

Installation is a direct replacement for the low-position lower mount: remove the factory plastic unit, test-fit the aluminium component to the existing bosses and secure with the original fasteners. After fitting validate suspension travel, check for binding and perform iterative setup adjustments to spring rates and damping to exploit the reduced flex.

From a tuning perspective, fitting this aluminium mount will tighten rear response and reduce transient flex, which affects mid-corner balance and initial steering bite. Use incremental tuning steps focusing on shock valving and front geometry to achieve optimal handling balance for competitive on-road performance.
