I had my first outing in the kart last weekend. With 17mm stubs I had 20mm of spacers inside and none outside. The rear was 1380mm.
It seemed to be okay but I needed to punch the throttle for the kart to turn out of the corner. I also checked inside rim to King ping and I’m running 20 to 25mm narrower than a 25mm axle!
So my question is, do you think it’s viable to run 25mm front axles and the current 40mm rear axle? I can get the rear axles to the maximum 1400mm width so all the benefit should come from the front change.
Anyway I had a ball in a frightening sort of way learning how to drive a kart. haha
