Kyosho YKW012 Kanai Tools Spanner 6.5mm 8.0mm

A double-ended spanner wrench from the Kanai Tools line, with 6.5mm and 8.0mm openings.

These two sizes cover the fasteners you actually reach for most often when setting up a 1/8 scale car. The 6.5mm end fits the ball ends on turnbuckles and camber links, which is what you turn when adjusting camber and toe. The 8.0mm end is offset deep, and that detail matters: it lets you get onto the shock standoffs where they sit recessed against the shock tower, a position an ordinary open spanner cannot reach without fouling on the tower itself.

Using a proper spanner rather than pliers is the difference between adjusting a link cleanly and rounding off a flat, and rounded flats on a turnbuckle end mean you cannot adjust it at all next time.

This is a pit tool rather than a vehicle part. It was designed by Yuichi Kanai and manufactured by Kanai Tools for Kyosho, and it is marketed for the Inferno MP9 range. A smaller 5.5mm and 7.0mm spanner is available separately.
