Fill a bottle 1/4, tip a bottle 25 degree's and then spin in a wide circular fashion - Not a perfect showing, but the water doesn't exactly sit on the bottom. Then add 200km/h and a bumpy surface for shits & giggles...
I've also done what... Maybe 100-150 limiter launches?
Then there are the cars with 380-400rwkw that run around Philip Island, on semi comps, with in-tank's and no failures.
Properly mounted that aren't a problem that anyone down here has been on the bad end of.
