Well after doing research and talking to an instructor and the regional director of NASA. I will be getting a 4 point cage installed with a built in harness bar that harness's can bolt into and plates welded underneath the car that the harness lap belts can bolt into. And some schroth 5 point camlock harness's because they are DOT and SFI 16.5 approved.

 

5 point camlock harnesses, DOT approved for an Evo?

 

what do you mean for an evo?

 

Ha, check that out! That must be a new development. Well, I admit it - I was wrong in this regard. Still scratching my head how that can be effective when there are known reports of the HANS slipping out of regular harnesses that do not have a ASM breakaway. The ASM breakaway basically extends the belt by a few inches, essentially making the belt looser. This creates a greater opportunity for the Hans to slip out from under the belt....

I understand, I'm in the same boat. I also made a few compromises in my setup that is not an ultimate configuration but better than not having anything at all.

Important part is that the drivers understand their setups and their limitations and are willing to accept the risks associated with it. Seems like you do!

 

There's a difference between meeting the certification requirements and actually being approved in a given application:

And the Vehicle Reference List

They haven't gotten very many applications actually approved by the DOT.

 

I worked directly w/ HMS Motorsport (I believe they are the main US importer for Schroth) & the mounting point chosen is an approved mounting location. The Schroth listing has not been updated to show the possible EVO Mounts

The Autocontrol is a basic 3 point high perf street harness & occasional track day. You can still run your stock belts if you choose. I run my Autocontrol full time.

The rally 4s when into my X without too much trouble. I had to get a little creative to be able to keep the stock belts but it all went in very securely.

 

+1 for HMS and Schroth, best in the biz.

 

Think they could update that then?

 

I think I'll be fine with schroth 5 point harness's.

 

IMO, I would do a couple HPDE/trackdays before you go turning your street car into a not so streetable car. If you're new chances are you won't be going fast for a few events anyways (learning curve) and while you're at the track you can talk with others, look at their setups and sit in different seats to see what you want to do.

FWIW, I've been tracking my car for years with nothing more than a set of Schroth Ralley ASM 4-point harnesses. most clubs accept these now and if they don't I can always just run my stock belts, like I do on the street. YMMV.

 

I would not use competition belts without a roll bar! Use a 3" lap belt with the stock 3 point. The waist belt will keep you snug in the seat and the 3 point will act as designed so in the event of a roll over and roof collapse you will not be held in a upright position. I tried to alert the BMW club years ago when I watched a 3 series roll over at Lime Rock. The roof came down to the top of the passesnger door and would have killed the instructor if he had been held upright by competition belts.

 

i agree, i don't think any 4 point harness are safe for track without roll bar, even with ASM since it still hold you upright in a rollover.

 

Probably mentioned by now, but it's worth mentioning again. Many lightweight seats are designed to be used in conjuntion with a roll cage. Many require attachment to the hoop bar for structural rigidity. In a hard impact, the seat will break if it's not properly attached to a structure behind it.

 

if the seats are FIA rated, the seat back shouldn't break.
