Harnesses with Stock Seats

[gleek48]

I have a question for those of you who have put harnesses in with stock seats. I am likely going with the Schroth Four Point ASM belts with a harness bar and am wondering how to order the belt ends.

I have been working with Pete at TDS to order some four point ASM harnesses and wondered if you were able to connect your harnesses to the stock factory seat belt bolting areas. If so, did you need any special attachment accessories or ends from the harness mfg? I was thinking of going with the standard bolt in (non removable ends).

Thanks!

I’m also planning on using the Schroth Profi II ASM Belts and will mount the lap belts to the rear seat bolts using Schroth B23A brackets. I called Schroth and discussed and this should work fine. There is very little room on the tunnel side of the seats but I have the brackets and have looked at it and it should work. If you’re ordering two sets of belts make sure you order a left and right one. A couple of other items: I had Schroth Profi II belts in my Boss and had the lap belts setup as pull down. With the ASM I ordered them as pull up. I also asked Schroth about the washers that come with the brackets and if they are necessary to use. I was told they are not needed and I plan on using the brackets between the bolt head and the seat rail.

Thanks Rick again!

A few follow-ups:

1)Will the B23A brackets allow for appropriate adjustment of the belts by being able to rotate around the T50 Torx bolt?
2) Do the harness brackets go between the bolt head and the oem seatbelt bracket OR between the OEM bracket and seat/floor?
3) Does anyone know the appropriate torque level for these two bolts?
4) Why pull up vs. pull down on the ASM belts?

Thanks again!

1 The brackets don't rotate and you don't want them to. The belts move on the brackets.
2 The brackets fit between the bolt head and seat rail.

4 I think pull up is more ergonomic and will allow you to pull the lap belts tighter. This is especially important with the four point ASM system. Either way is fine but I've used belts in a pull down mode and think the pull up will be better.

I went a different route.

I'm sure this will make some of you cringe. LOL

I don't run any sanctioned races.

Works awesome.






Actually cut and placed mine further forward than this pic.

Yep that makes me cringe!

Why not a 6 point? No cut required.

How would you mount the 6 point? Also, does anyone have pics of how their shoulder belts are ran with stock seats?

Crotch strap goes between seat back and bottom attaching at the rear with other belts.

I didn't think it was recommended or safe to sit on your sub straps with a 6 point setup.

Car safety is a personal decision and anything short of a full roll cage, fire suppression system, race seat, Hans, fire suit and anything else you can think of is a compromise. Determine what you're comfortable and use it. Many of us have used the sub belt mount below but I'm going to use the Schroth ASM belts in my GT350.

And if it's mounted properly it does it's job!
The lap belt is still supposed to take most of the load, the anti-sub belts job is to help keep the lap belt where it can do its job.

Having them incorrectly located is not an option, it's makes their use dangerous!
