Lets see your aftermarket seats!

I would be hesitant to do a fixed back bucket seat and a set of harnesses at the same time. In a sudden impact where you're slowed down instantly the only thing that will move is your head and you'll definitely break your neck. I would only consider a seat retaining the factory belts. Race car safety equipment is designed as a system. Roll cage, seats, harnesses, HANS device... It's like those guys that get roll cages on a street car and just leave open, exposed metal tubes without wrapping them in foam. Without a helmet, HANS device and harnesses you'll end up cracking your head open like an egg.
