MUUMUU,

How much camber do you have? With more neg camber it will move the top of the tire in.

If you have a rear sway bar you will want to disconnect on link for Big Willow if you are already noticing a loose condition in Solo II.

AutocrossCuda can confirm.

Are all 4 tires the same size? if so you can rotate.

Maybe we will give you neg camber at the track!
