At present it only has leaf springs for fore/aft and torque reaction control. They are composite of decent rate (250lbs.) for the rear corner sprung weights (<500lbs.), but aren't enough to keep things under good control.
Greg, the motion you are talking about is axle lateral movement through pure vertical travel - the watts link eliminates this movement. As the car rolls about its rear roll center, on the outside rear corner, the outer fender lip tends to move "away" from the tire (since it is well above the roll center height), and the inboard top of the tire gets closer to the inner fenderwell.
