I set one of my karts up for a friend. We fit a Tillett T10 XXL seat and so we needed to expand the struts a good bit. I did fit an old axle over the right side strut and bend it outward a bit. Mind you, on this CRG frame it was a bit difficult to move it as to the way the strut is fitted to the frame. But we did end up getting just under an inch of rightward expansion. We scaled the kart and still had more weight left than right, so it was the right thing to do. With a driver of his size you’re already over weight minimums, so no chance to add weight and re-balance without that weight penalizing you’re laptime.
