Tamiya 63808 Mini 4WD Tune-Up Reference Guide (Japanese Text)

*Please note - this guide is mostly in Japanese, not English.*

This printed reference supplies targeted tuning notes for Mini 4WD enthusiasts, concentrating on chassis balance, mass placement and routine trim changes. Sections are organised to show part orientation, contact areas and recommended adjustments to wheelbase, rollers and traction features without asserting guaranteed performance improvements.

Written for workshop use, the manual describes how tuning choices can change handling on both hard and carpeted tracks, and highlights simple verification steps to run after every modification. Diagrams and illustrations make part orientation and placement straightforward so setups can be compared and refined sensibly.

Treat this guide as a workshop companion when testing setups, recording each change and preserving original measurements so you can return to baseline settings if needed.
