I use mine as my only car.... Well I do have the Healey for a nice day driver, but essentially the FiST IS my transportation.. I put in the mountune springs and the car rides better than stock, corners flatter than stock and is easier to wash being about an inch lower. I've put in a trunk brace and most recently the front shock tower brace. With that little bit of bracing the car feels more solid, "of a piece" as they say. (I don't track the car. I intend to keep it for a very long time)
