eesh... Aftermarket seats generally don't hold up well in crashes. On the previous gen civic taking out the OEM seats not only removed the side airbag that was built into the seat but if the system detected one airbag gone it disabled all of them leaving you with little protection. It is also a huuge liability if you are in a crash and your insurance finds out you had a disabled or removed safety system.
The seats don't have to go through the same testing that OEM seats do for impact and the mechanism that allows the recline is usually pretty weak. Also the "racing seats" generally need the harness bar or roll cage to prevent this from happening. First of all, the only safe place to mount a harness is to a bolted in roll bar or roll cage. Anywhere else, and it is likely to fail. 4 and 5 point harnesses decelerate your body instantly in a crash. This means that your body won’t move forward, but your head will. This will result in a debilitating or fatal neck injury, even in a low speed accident. . This is rectified with the use of a HANS. Don’t think you need a HANS? Ask Dale Earnhart about the HANS. Also, if you have a front airbag, you won’t reach it with a 4 or 5 point harness, rendering it useless.
This vid is of Bride seats, not recaros I know.
Like most of the people who love racing, I've always wanted a set of highly bolstered, aftermarket, race seats. I never wanted to deal with the airbag light on my dash, and didn't really want to lose the use of some of my airbags JUST so I could have super cool street cred seats.. I realize this is a really old thread, but Nix is right on the money with everything he's said. In 2011 while driving my FG2 to work, I was t-boned by a 17 year old girl driving her daddy's Mustang GT around 45mph. After the wreck I was completely in shock and only remember ONE thing that was said to me by one of the cops. He said that if it hadn't been for the seat and side curtain airbags, I'd probably be dead. Pretty heavy words for a guy in total shock.
The aftermath of the t-boning:
Just give it a little extra thought before switching your seat out for one without airbags.
