I guess what I am saying is that this conversation isn't going to get you much of anywhere. You are on some ebay coils on stock struts. The handlings MAY actually be worse than stock (although feel better). For instance, do you know you're front and rear springrates? That would be a good place to start.

Since you are on stock struts they can still extend as long as they could with the stock springs when unloaded. The wheel is not actually lifting it is just REALLY extended. The sensation you MAY feel is the actual upper mounts from the struts coming away from the top of the spring.
