Thanks guys. No, I'm not going for the rice effect Rob. I have a hard time staying planted in my seat during autocross which makes it harder to stay focused on steering and shifting when your body is moving around. By the end of each run, my *** is planted on the door. I read at TeamFC3S and FC3S.org about the Autopower race roll bar. It looks good and is legal for SCCA and many other organizations even for some road racing. It has the optional harness mount bar. Based on everything I read, if I want to do this, I should do it right and get the Autopower or a cage. The Autopower is $350 for the FC and they build it custom for our car.

 

Here's a link to the pic of this guys interior (from TeamFC3S) with the Autopower race roll bar and harness mount:

I'd suggest putting in a rollbar/cage before considering harnesses. Seatbelts are designed to allow you fall forward enough to save your head in case of a roll over where the roof caves in. If you were in a harness you'd be stuck upright with your head only inches from the roof. If the roof were to collapse in a case of a roll over you'd experience severe head trauma and spinal compression. doesn't sound like fun does it?

 

I agree, if I do this I'm going to do it the right way.

 

it's only your life right

 

it sounds like you have most trouble with lateral movement in your seat, perhaps simply swapping out the stock seats for some lightweight race seats with more side bolstering will prove sufficient?

 

I think you got a slow responce since there is a thread about 10 threads down that talks about it.



Get some piping thats even stronger then the strut bar (since its holding your life) and fix it up for yourself or have a shop do it with some harness points

 

Right, thats the main issue but I don't think most of them are designed to work with stock belts. I mean the stock belt would go over top of the seat sides instead of through the holes that they put in them for harnesses. You never know, I could still roll the car autocrossing. Some of these lots are pretty bumpy. I could see myself fishtailing and rolling it.



I think best bet is to get a seat and a harness and use just the lap belt until I have money for a good rollbar. Actually that doesnt make any ****** sense either because on the street I'd be screwed in a front end collision with no shoulder belt.

 

Here is the seat I am thinking about

 

Look, he doesn't need all that crap if he's solo autocrossing.

If you're ONLY using it for the autocrossing, and to prevent lateral movement by compressing yourself into the seat, then you've got the right idea with the strut bar. Chances are you'll never see loads high enough to even flex the bar, let alone bend it. Don't believe me? Go try to bend that brace. The stock FD one I could bend in half with my bare hands - that was a bad idea to mount any harnesses to.. But most solid aluminum ones should be PLENTY stout for autocrossing.



I don't understand why you guys think this is so dangerous?
