i have the s&w 8 point cage with sparco cam 4 point harness in my dc. I mounted the shoulder belts to the roll bar, but the bar sits too low and it makes a 60 degree angle from thte belt to the bar. Ive read that its not supposed to be more than 20 degrees or it can cause spinal compression so..... now what are my options on mounting the shoulder belts? I was thinking of welding another bar higher just to mount the belts. anyone have any other suggestions?

 

are you mounting it to the horizontal bar? was this a custom built cage or production?

 

yea, im mounting it to the horizontal bar. when I had my other seats in, the bar was right behind the belt holes so it would have worked perfectly, but I got the jdm recaro's and those seats sit higher.

 

weld a higher bar.

or, lower the seat.

My guess it that you don't need to worry about spinal compression because your shoulder harness belts will pull your lapbelt up from your hipbones so that you end up submarining (i.e. the lapbelt stops your forward momentum by your guts, not your hipbones). Plus your cushy seat will compress letting you sink deep down so you still won't suffer spinal compression.

 

Andrew, you're probably right....BUT....I'd make a decision right here

1. Swap the old seats back in
2. If you REALLY wanna keep those seats in, you need to remove the cage, have the bar raised, re-welded, and re-painted.

For any formal track time or peace of mind, I'd recommend going the safe route instead of risking your f*cking SPINE for God's sake...

 

I was trying to be an a$$ with my comment. I was trying to say he's likely to have a different type of injury than the type he's worried about.

Personally, I think he should :

a) if he's gonna run his current seat, then he should:
....i) use the OEM belts rather than harnesses
.... ii) get a 4pt harness that's designed limit submarining and have the harnessbar fixed.

b) If he's going to put his old seat back in, then he should
.... i) use the OEM belt rather than harnesses
.... ii) get a 4pt harness that's designed to limit submarining

Eitherway, I would ditch the camlock 4pt he's got or see if the camlock can be used to add a sub-belt.
