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

Low-position rear lower mount

This aluminium rear lower suspension mount is an RC-scale replacement tailored to Kyosho FW05-R chassis using low rear arm geometry. Built to be stiffer than the factory plastic part, it offers a firmer attaching point for rear suspension components in on-road configurations.

Compatibility is specific to FW05-R chassis models; confirm your chassis identifier before purchase. The mount affects rear roll centre and the way the rear arm transmits loads to the hub assembly when paired with your existing arms and hubs.

Fitting is recommended for hobbyists comfortable with basic assembly: remove the original lower mount, test-fit the aluminium replacement to the mount bosses, then refit using the original screws. After installation check for full travel and ensure there is no binding, then re-evaluate ride height and toe after initial track testing.

As an upgrade, aluminium lower mounts reduce flex and sharpen rear response, which can alter mid-corner balance and transient steering behaviour. Make measured setup adjustments to tune the chassis to your preferred handling balance.
