Nice seats.
You seem to have a death wish with the way that 4 point harness is installed.
Make sure you have time to take them off if you feel you're gonna get into a head-on collision...

..crushed vertebraes coming right up. I'm not kidding man, watch it with those shoulder straps going back down along the seatbacks.
I like those seats a lot though! For the price, I might pick up a set!
