Tamiya TT01 & TT02B Alloy Brake Disk Hex Adaptor - TT010A/DISK by GPM  [TT010A/DISK]

Hex drive adaptor for TT-series brake disks

This alloy hex adaptor is supplied as a 4pcs set and serves as an RC-scale replacement to accept hex-driven brake disks on Tamiya TT01 and TT02B chassis. It alters the drivetrain hub interface to accept aftermarket alloy disks while preserving the standard TT-series wheel hex mounting geometry.

Manufactured from machined aluminium to prioritise dimensional accuracy, the adaptor is focused on repeatable alignment and stability rather than extra features. It provides a firm mounting surface so brake components remain concentric to the wheel hub during setup and trial runs.

Installation advice: check your wheel hex and hub clearance before fitting, use the right hex driver and confirm screw thread engagement, and inspect for any interference with suspension or drivetrain after initial fitment. Apply torque sparingly to avoid damaging small hub threads and verify clearance with tyres installed.

For hobbyists fitting alloy brake disks to Tamiya TT01 or TT02B, this GPM adaptor offers a machined aluminium mounting option that helps keep chassis geometry intact during tuning.
