Schroth harness question
The links to the pictures in the "how to" thread for the Schroth 4pt harness are all dead and I'm trying to figure out what to do with the OEM seatbelt. I'd be using the Schroth harness 100% of the time but I'm trying to avoid a dummy light on the dash for driving around with the OEM seatbelt unbuckled. Besides the dummy light, I'm concerned it disables the airbag too. Does anybody have pics of their setup they could share?

I just run the OEM seatbelt around the back side of the seat and buckle it while I'm using the harness. Alternatively, get a spare seatbelt from a junkyard or something and just cut out the part you need.

I would never use a 4 point harness on the street. Unless it is a track only car (in which case you might as well go with a 5 or 6 point harness), then you should use the factory belt. It will help you slide underneath the lower belt in the event of a roll over and crushed roof. A 4 point will just lock you down into the seat.

Must be a USDM or GSR thing...I never got a seatbelt light when I put in my 6 point Schroth harness.
Trickest part of the Scroth harness install (besides drilling the floor in my case) was finding a proper bracket to clip the right hand side lap belt to....I just ended up getting a spare seatbelt buckle, cut the buckle off, reversed it and screwed the bracket down along with the OEM seatbelt buckle assembly.
Of course my centre console is out as well - but I mounted an extinguisher there instead.

The only 4pt harness I would consider for street use are the DOT approved Schroth belts with ASM, that are designed to prevent the submarine effect and let your upper body go forward. I would stay away from any other 4pt belt, even for a track only car. Instead go with a 5 or 6pt with a roll cage as Rancid already stated.

Is ASM an electronic part that works in conjunction with the Schroth harnesses? Also after reading Rancid's post and doing a little research of my own it might make sense to wait until I have a roll cage on the car before installing a harness. I think for autox this might be a really cool little upgrade but for road courses where speeds are higher and rollovers can happen this might not be the best way to go.

I use the Schroth 4pt with ASM at the track (HPDE, not racing) because the probability of frontal impact into a tire wall or guard rail is much higher than a roll over. I prefer to have the added protection in a frontal impact over a 3-pt and the fact that I don't have to fight to remain in the seat helps me concentrate on the actual driving. For a roll over, due to the ASM break a way strap, there will be enough slack to bend my body forward in a roll - not as much as a 3pt, but enough for my personal comfort level. It is a trade-off and you should understand how each decision may impact you. I'm installing a roll bar for this year for added protection.
Ultimate solution is a cage + race seat + 6 pt harness + neck restraint. But many people don't have that luxury so it is a trade off based on your budget and the risk you are willing to take with your life. You should be comfortable with the decision you make and each person's requirements, risk and comfort level differs.

Ive been considering the Autocontrol II......I ran it years ago on my VW GTI....Very comfy.....http://www.schrothracing.com/product...autocontrol-II
Install the inertia reel at the left rear passenger anchor point.......Review the instructions & its an approved location for the reel.....Use a switch to disconnect pwr & youre fully locked-in for track use
You guys know, running a solid 4 point is not safe unless youre using the "Hans".........The Autocontrol uses a sensed inertia reel & gives you freedom of movement until the sensor sees enough force to lock up
Please review & reply as I appreciate your comments...........Minus-Pre
BTW.....I called Schroth today to review

We recommend that only non asmŪ belts be used in competition harnessbelts.
Racing harnesses without asmŪ must be worn with an anti-sub strap!
