The 22mm rear bay went on today in the wet. With my current suspension set up the 22mm Signature Swaybays, (the bar was so big it looked like it changes weight distribution) reduced understeer, but in no way could over steer be induced, in the wet. The rear diff could be felt as more active. The car just grips and goes. The car feels AWD no RWD characteristics, despite "tossing" in the wet, just grips very safely. These are amazingly good handling cars.....
