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

Hex adaptor kit for TT-series brake disks

This machined alloy hex drive adaptor is sold as a 4pcs kit and functions as an RC-scale replacement to accept hex-driven brake disks on Tamiya TT01 and TT02B chassis. It modifies the drivetrain hub interface to accept aftermarket alloy disks while maintaining TT-series wheel hex mounting geometry.

Forged from machined aluminium to ensure dimensional repeatability, the adaptor focuses on alignment stability. Its purpose is to give a reliable, concentric mounting surface so brake disks remain true to the wheel hub during setup and testing.

Installation checklist: confirm wheel hex and hub clearances before fitting, use the correct hex driver and verify screw engagement, then inspect for any interference with suspension or drive parts once fitted. Apply conservative torque to protect model threads and check clearance with tyres mounted.

For modellers updating brake systems on Tamiya TT01 or TT02B, this GPM adaptor provides a machined aluminium mounting choice that helps with straightforward installation of alloy brake disks while conserving chassis geometry for tuning.
