100mm extension for max 16mm pedal which are usually found at least in Tony kart / OTK karts. You need 3x basic 10mm M6 nuts and 25mm minimum M6 Allen head bolts per pedal, also added holes for one zip tie to add some peace of mind. I sharpened the bolt ends a little bit so it bites nicely in to the pedal.

File includes both left&right side.
