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

Alloy hex adaptor for TT01 and TT02B hubs

This precision alloy hex drive adaptor is a 4pcs RC-scale replacement designed to accept hex-driven brake disks on Tamiya TT01 and TT02B chassis. The set converts the drivetrain hub interface to accept aftermarket alloy brake disks while keeping mounting geometry aligned with common TT-series wheel hexes.

Machined from aluminium for dimensional stability, the adaptor is intended to deliver consistent concentric mounting rather than added functionality. Its role is simple and reliable: provide a rigid, repeatable attachment point so brake disks remain centred relative to the wheel hub during tuning and testing.

Fitment tips: confirm wheel hex size and hub clearance before installation, use the correct hex driver and ensure proper screw engagement, and check for any contact with suspension or drive parts after first fit. Tighten hardware carefully to avoid stripping model threads and verify running clearance with the tyre fitted.

For builders upgrading brake assemblies on Tamiya TT01 or TT02B, this GPM adaptor gives a machined aluminium mounting option that eases fitting of alloy brake disks while preserving chassis geometry for setup work.
