9 was pretty good. It reminded me of when I used to build 67-69 old Camaros back in the day. Convertables in that year was hard to find the weights on each corner of the car. Even the ones in the truck. The weight was on the 4 corners to offset the loss of the weight of the hard top. With out that added weight they would flip easy on curves with just a bit to much speed.
But people being people thought it was dumb to have more weight in the car. Some paid a heavy price for thinking that. Sadly their passengers did as well.
