With no karting league at the beginning of winter due to covid, and waiting for parts to come in I made a decision to cut up the rear suspension and change the converging 4-link to a parallel 3-link. Getting decent geometry while keeping the back seat is a challenge. The result is an 11" upper link, offset 9" from center, and a lot of adjustability for anti-squat.
Instant center location is improved a lot over stock, all roll-bind is eliminated, and I have full freedom to adjust roll-center height. The only unknown is whether the 9" offset will work... I'm not smart enough to figure out the math needed to calculate that, so I will just try it and if it doesn't work, I will add a link to the other side and turn it into a parallel 4-link.
I also added a drain plug while it was apart... If you ever put a Ford 9" in anything, get the drain plug option. You're welcome.
