Kyosho FW05-R rear lower suspension mount by 3Racing FW05-002  [FW05-002]

Rear lower suspension mount (Low)

This aluminum rear lower suspension mount is an RC-scale replacement part intended for Kyosho FW05-R chassis owners who use low rear arm geometry. Machined from aluminum for rigidity, the part replaces the stock low-position lower mount to provide a firmer mounting point for the rear suspension in on-road setups.

Compatibility is limited to FW05-R designated chassis versions; confirm your chassis code before purchase. The mount's role is purely structural within the model's rear suspension, affecting rear roll center and how the rear arm loads under cornering when paired with existing hubs and arms.

Installation is straightforward for experienced model builders: remove the original plastic lower mount, test-fit the aluminum part to the existing mounting bosses, then secure using the original fasteners. After fitting, check suspension travel and clearance to avoid binding; re-check ride height and toe after a test run and make incremental tuning changes.

In tuning terms, switching to an aluminum lower mount can tighten rear response and reduce flex under load, so expect changes in mid-corner stability and transient steering feel. Use incremental setup adjustments to balance the chassis with front-end components and shock settings.
