Back in my sports car obsession days, we had an assortment of front and rear antiroll bars for the Datsun roadster we campaigned at various autocross and gymkhana competitions in central California. Depending on the layout of a particular course, we would swap bars to change the handling characteristics. Maybe it helped- - - -we won a lot of class trophies and a few "overall best time" on the short, twisty ones.
