TAMIYA M05 257mm Wheelbase Upgrade M05-31/LB by 3Racing  [M05-31/LB]

Precision wheelbase adjustment for M05 chassis

This extension kit is engineered for the TAMIYA M05 chassis and is identified as 3Racing part M05-31/LB. It establishes a 257mm wheelbase to allow focused setup comparisons and handling analysis while retaining original drivetrain geometry.

The design intentionally only modifies the wheelbase dimension and preserves mounting locations for electronics and drivetrain components. Fitment follows the standard M05 mounting pattern and is intended for competitive setup work and comparative testing on 1/10 scale touring platforms.

Installation requires controlled disassembly of the affected mounting points and accurate relocation of subframes to the extended positions; precise alignment and post-fit ride-height calibration are essential for repeatable handling data. This technical summary is aimed at racers and tuners rather than a step-by-step assembly manual.

Compatibility notes: Confirm M05 mounting pattern match prior to installation and verify included hardware with the seller to ensure correct fitment for testing and tuning.

For setup-focused users, this kit provides a controlled method to assess the influence of wheelbase on stability and cornering behavior while preserving the platform's core mechanical and electronic layout.
