But it is much easier to control a car with race seats, less sliding around and gripping the wheel to stay in place. And it is safer if you also add a roll bar. It is a tradeoff between street comfort and track comfort, like most track mods.
If anything your upper body can be pulled outside the window exposing you to the ground during a flip which is what I mentioned save the guys life having the recaro seat. Being ejected from a car is possible, I am just stating the possible events that can occur and what a racing seats help to prevent.
