Naraku variator spacer washers.
These fit in between the front pulley and the variator shaft and allow you to space out the front variator pulley for fine tuning your variator.

Spacing out the front pulley slightly can often significantly improve initial pickup performance where this is a problem, for example when fitting a rev happy sports pipe to a standard variator.

This variator spacer kit contains 30 shims... 10x 0.1mm, 10x 0.2mm and 10x 0.5mm thick.
