Harness Install Tips - Brey Kruase - Schroth
I am getting ready to install my Brey Krause harness bar and I am looking for a harness now. After all the reviews and searching...... I have decided on the 4 Point Schroth Profi II ASM FE with the factory seat.
The question is the Brey Krause is designed to wrap the harness around rather than bolt on to it, I believe. Does anyone have any guidelines for installing the harness with this harness bar?
Can I just use the factory seat bolts in the rear for the lap harness?
Any help or suggestions would be greatly appreciated.

For wrapping your shoulder straps around a harness bar, see this video:

for anchoring the lap belts there is no facility for that on the stock seat rails/mounts. maybe someone else will chime in with what they've done.

Take a look at this Scroth document. Page 12 has some good info on angles required for safe installation of the lap belt and shoulder belts. About page 24 there is some good info on installing the harness straps.
http://www.schrothracing.com/sdocs/2...structions.pdf
A harness is really only for the track - it hasn't been tested with the federally mandated airbag system, which is an integrated system that is designed and tested to work with the stock 3 point belt system.
As far as a 4 point system, many organizations that sponsor track days don't allow 4 point harnesses (PCA, Chin, etc.) - they require 5 or 6 point systems for ASM restraint.
They also have a requirement for a harness system to run through pass-through holes in the seats, and PCA for one requires that the seats be manufactured with those holes and not modified, so stock C6 seats are not acceptable for use with a harness system.
Additionally, there is an "equal restraint" rule that says that if you carry a person in the right seat (instructor, observer, passenger) that if you have a harness system for the driver, you must also have one for the passenger.
I assume you're going to install race seats for the track and take them back out for street driving - is that right?
Many states reportedly don't allow racing harnesses for use on the street - they haven't been tested with the airbags, etc.
If you do run race seats, you'll most likely lose the operation of your airbag. I assume you have side airbags, and a race seat in the passenger side probably won't have the PPS and will deactivate the passenger airbag. Nobody really knows (again, no testing has been done), but when the passenger and side airbags are deactivated, the entire SRS may be inop (driver's airbag, seat belt pretensioners, etc.).
With a racing harness that holds you erect in the seat, your body can't lean over into a safe area if the roof/halo collapses, so you really should have a good rollbar or full cage with a racing harness.
JMHO, YMMV!!!
Good luck, and show us some pictures when you get everything installed!!

I choose a 4 Point as it does not have an antisubmarine feature as I am not adding a roll cage. Based on my research if you do have a 5/6 Point harness roll cages are required by most sanctioning bodies.
I also know that the pass through on the seat is a requirement but is not required for the “Test and Tune” days I am running in which is just for fun. I am having a hard enough time getting to this let alone participating in any regular events as my schedule is really day to day.
I hoped to use eyelets for the harness attachment so that I could quickly remove the harness for normal driving, but if it is bolt-on that is acceptable also. I actually picked the Brey Krause bar b/c it was easily removable.
Hopefully in the future I can find the time and have the retirement in place to spend enough to do more racing. As a ME I can assure you I think about safety first and would feel much more comfortable with a proper racing seat, HANS devise, full face helmet, Nomex suit, 6 Point harness, roll bar/cage and fire suppression system at minimum. To be completely honest I have very little track time and would probably just pick up a cheap car first as the Z would be nearly impossible for me to drive and be competitive. I did the math years ago and after you figure the trailer, wheels, tires, safety equipment, travel and entrance fee’s, suspension, engine, transmission, lap timers/electronic, brakes……………………. I could easily spend $100,000 the first season and hundreds of hours.
Good luck, and show us some pictures when you get everything installed!!

No offence, but 4 points are NOT allowed at HPDEs. Need a 5 or 6 point with proper mounting seats. ie the shoulder harness must pass THOUGH the seat back not around.
Does not matter what Scroth says, that is moot. 4 points are just not allowed. Most HPDEs follow the PCA or BMW rules so might as well your self up so you wont be disappointing.
6 points are best as they have 2 sub belts. One sub belt tends to squeeze the family jewels
so you need:
1- Two new seats - Sparko Evo , Momo, Team Tech, Suzka Cobra ( non- leather )
2. two pair of seat rails to mount the new seats. OEMs are too tall.
3. harness bar
4. two sets or 6 point harness. with pull down straps.
5. harness mounting hardware
if your going to have a HANS device then you must have race seats and have them properly mounted.
your heading down a slippy slope with the mods. So I will you the best of luck
This is why some guys just buy a race ready C5Z T1 car for mid $20s. But then again that means a 3/4 ton pick up truck and a trailer.

You will find as stated above that almost no organization will accept 4 point belts. Call Joe Marko at HMS Motorsports (888.467.3269) and talk to him about your options. He is a recognized safety expert who works with some of NASCARs biggest teams, BMW CCA, PCA, etc. I have attended several of his seminars on harness installation and related safety issues. He sells Schroth harnesses, knows the product line very well and will provide the best advice you can get.

I talked with Joe today which was a HUGE help. I am looking into seats now and I will take it from there!!!
Thanks Again For Everyone's Help

Good to know, I have been reading quite a bit and have obviosly recieved poor information from what I qualified as good sources. For now I am not going to do anything until I talk with some of the techs/track junkies my local track some more.

I was also thinking about installing a 5 point or 6 point harness but was looking at the carvaggio race seats. They are leather but have the cut-outs in the back and use the stock rails. Have you encountered problems with "tech"ing a car with this setup?

I will hit my first track day in the Z on the 3rd out at HPT and I will see if I can keep up with the car!!!

On reading these threads on installing a 5 point harness on my c6 z06 my question is this. Can I fab a bracket that just bolts to the same bolts the back of my seat fits on to hook the bottom 3 points of my harness. I am not at a track where they make you buy racing seats but I don't know for sure would they accept that. I just don't want to butcher my car up and frankly the eye bolts that came with my Crowe harness are no better than the floor they are bolted to which is aluminum.
thanks
