Precision TT-01d Front Lower Arm Alloy Upgrade TT055D by GPM  [TT055D]

Precision front lower arm for TT-01d platform

Manufactured by GPM, this alloy front lower arm is supplied as one pair for the TAMIYA TT-01d platform. The component is CNC-finished for consistent fit and is intended as a direct replacement to improve rigidity over stock plastic arms without altering mounting geometry.

Integration and function: The part installs into the front suspension mounts of TT-01d chassis using standard pins and fasteners. As the lower suspension link, it contributes to camber stability and steering precision when used with factory uprights and tie rods.

Performance notes: The alloy construction reduces flexing under lateral and braking loads, offering more consistent alignment readings during setup changes. Use this arm when precise feedback is required to evaluate damper valving, toe adjustments, or anti-roll bar tuning on circuit-focused on-road cars.
