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

Low rear lower suspension mount

This aluminum rear lower suspension mount is a direct-fit replacement for Kyosho FW05-R chassis running low rear arm geometry. Machined from aluminum to reduce flex, the part replaces the stock low-position lower mount and gives a firmer rear mounting point suited to on-road setups.

Compatibility is restricted to FW05-R designated chassis versions; check your chassis code before purchase. The mount serves a structural role within the rear suspension and alters rear roll centre and load transfer through the rear arm when used with the existing hubs and arms.

Installation is straightforward for experienced builders: remove the factory plastic lower mount, test-fit the aluminum unit on the current mounting bosses, then secure with the original fasteners. After fitting, inspect suspension travel and clearance to prevent binding; re-check ride height and toe after a short test run.

From a tuning perspective, switching to an aluminum lower mount reduces flex and tightens rear response, which can change mid-corner balance and transient steering feel. Make incremental setup changes to harmonise front-end settings, shocks, and tyre choice.
