Technical aluminium rear arm for GB-01 platforms

This CNC-style aluminium rear suspension arm is specified for Tamiya GB-01 and GB-01T chassis, replacing the original plastic arm to provide a firmer and more repeatable rear suspension mounting point for fine tuning handling characteristics.

Intended for use only on GB-01 and GB-01T platforms, the arm is suitable for hobbyist racers and serious tuners who require consistent attachment geometry. The light blue anodized surface improves wear resistance under normal operating conditions.

Installation and tuning notes:

  • Fit: Manufactured to match the standard rear suspension mount locations on GB-01/GB-01T chassis; verify mounting alignment and suspension articulation during a trial assembly.
  • Tuning role: The aluminium arm increases local stiffness at the mount, affecting rear-end compliance and feedback; expect changes in traction and roll response that can be tuned with damper and spring adjustments.
  • Maintenance: Inspect mating hardware, check hole clearances and confirm fastener torque after initial installation and following early test runs.

What tolerances should I check when fitting?

Check alignment of the pivot holes with the chassis mounts, verify free suspension travel through the full range and confirm there is no lateral binding against nearby components.

How does this arm affect dynamic weight transfer?

By increasing mount stiffness, the arm reduces local compliance, which can sharpen rear weight transfer and change transient behaviour; tune damping and anti-roll settings accordingly.

Recommended post-install checks?

Perform a geometry check, confirm screw torque values, and run a series of measured laps to assess handling changes before committing to permanent setup adjustments.
