This precision machined aluminium rear lower arm kit is a high-value upgrade for the Tamiya FF02 chassis, intended to replace the stock plastic lower rear arms while improving component life and suspension consistency.
These arms locate the rear suspension links and wheel hubs; reducing pivot compliance at the lower mount preserves geometry under repeated load cycles and supports more accurate tuning of rear roll and toe behaviour.
Installation uses the OEM rear lower arm mounting points. Replace arms one side at a time to maintain setup, verify hinge pin and ball stud seating for correct articulation, and confirm free hub rotation before final torque. Follow with a rear toe and camber check as part of baseline setup verification.
The kit is suitable when replacing degraded plastic arms or when seeking a more stable and predictable rear suspension platform for club competition and practice sessions.
Compatibility: Tamiya FF02 chassis
