The SCCA has "outlawed" the Fiat 500 for autox competition due to risk of roll-over. In stock class you can run R-compound tires and by their formula the 500 is prone to rolling over....so you cannot compete with this car. 
Anyway, the formula is relatively simplistic and likely not correct.
For the record, I do not own a Fiat 500, but was hired to do a bunch of test drives at the Calgary New Car Show from Wed-Sun last week and was assigned the 500.....so I logged some hundreds of km. in a Sport with an auto, sun roof and sirius radio ... Long and short of it, I did not feel that the car was overly tippy.
Anyone find out what the height of the CG of the car is? Or any other roll-over data/information?
It would be a shame not to be able to autox this fun car!
Oh, and I've been autoxing since before Fiat left the North American market.
TIA,
Reijo
