Personally, I've been too afraid of screwing up the drive train (really BIG $$$$) - I have not chirpped the tires on a straightaway, but the rear really wants to get loose if I stomp on it when the wheel is turned (ie, pulling out from a perdendicular road) - with the Dinan S2 setup, there is no typical 'hesitation' when accelerating from a stop - the weight of the X5 also inhibits breaking traction
