This was my chassis. I picked it up from Mike at Kartfest. I ran it for a couple years in UAS before I quit kart racing. I did not fall on it's face in the dirt as someone said although I struggled with it it at times. Too many variables for a one man team to learn. I am sure it would have won some races if it came with Mike Clements as a crew chief although he helped me as much as he could with our phone conversations. You could adjust the height, camber, toe and tire pressure of the 5th wheel. The loop could be "unbolted" for spring action or bolted to take it out of the equation. I ran a Briggs 305 one year and then a Sudam 131 the next. It was fun.
If you want to know the truth I think the 5th wheel was a gimmick to divert attention away from the loop. An old racers trick lol.
