I have what I was told an 04 Phenom (has no ID plate) and I’m looking to do some upgrades to the front end to help my exit speeds. The kart is fast down the straights and handles the corners pretty well but the leader last season eat me alive on exits. I’ve heard and researched a little about the spindle spacer adaptor kit but I’ve been told I need to increase my caster angles also. Any advise or tips would be greatly appreciated.
