This is actually fairly common in Formula Student cars. They often use decoupled heave/roll suspension systems, where one spring/damper is for the heave of the entire axle and another one for the roll on the axle. It has some advantages over separate springs, but I'd have to ask our suspension guys.

The graphics in this article show its function fairly well, but don't explain the calculations either

Recently, some teams have added the hydraulic relocation of dampers, and some (like Dresden) even have software control of them.

Isn't the go-kart suspension still somewhat competitive, though? I'd heard of teams that have suspension travel for passing tech and then jack up the rates afterward.
