Mark Walker sent me a pic of the rear anti roll bar today and I noted that in his pics the flats of the blades were upright but I have my front ones the other way around with the flats pointing side to side, it has not dawned on me that this is how you adjust the roll stiffness (if that is the correct term) of the bladed bar...Mark explained it well by saying that you think of it like a plastic ruler, flat pointing up is full soft and flat to the side is full stiff....my car has been running in full stiff (a bit like me after a lap dance)
