you see most injuries that get blamed on suspensions seats are actually being caused by totally improper mounting of seats, seat belts, and in some cases even the suspension seat choice itself.
A standard Corbeau seat is NOT a racing seat and is not even kinda safe enough to be doing any real racing in. The headrest comes up to the base of your skull on the normal base level seat...that is not OK. Add in the fact that you see so many of these seats leaned so far back that the driver is having to lean forward to see anything and their head is already pre-loaded for whiplash. Add in belts that are mounted as what seems to be an afterthought is a lot of rigs.... and you have a recipe for disaster.
A properly mounted true racing suspension seat with proper (and properly tightened, more on this below) belts, is going to be more than safe enough for anything you would ever do. The containment seats have the advantage of keeping your head and neck from moving as well as keeping your body contained side to side. They do nothing to protect you vertically.
Another major point that is often overlooked is how much padding is in the belts. This comes in the form of actual belt pads (which have no place in a true race car), clothing as padding (too much clothing, jackets, etc on some guys), and then just simply body fat. The simple fact that some peoples bodies are more...umm....compressible than others
can lead to some movement in a bad crash too.
Containment seats have their place, they work great for some guys. But a properly installed (and proper design seat itself) suspension seat will work for 99% of guys out there in my opinion
