The Tamiya 69575 JR Circuit Wave Section gives Mini 4WD builders an easy way to add vertical rhythm to Japan Cup Junior Circuit layouts. These parts are great for testing handling across multiple laps.
Each piece is injection moulded in white ABS for consistent strength and a smooth finish. The sections are built to slot into a 3-lane Japan Cup Junior Circuit so you can rearrange them quickly between practice runs.
Wave sections let you replicate bumpy rhythm changes to assess chassis behaviour and tyre choices. Whether tweaking gear ratios or testing stabilisers, these modules help highlight setup strengths and weaknesses.
Compact and reliable, these wave sections expand your track options and support more focused setup sessions for Mini 4WD cars.
