5-point harnesses for Boxster - whatelse do I need

[gandrade1]

Hi guys,

First of all my delayed, but sincere, wishes of a happy New Year to all. May 2009 bring you a lot of peace, health and accomplishments…

Now, to my first project of the year – I am thinking of installing 5 or 6-point harnesses on my Boxster. I was quoted $900 only in labor! Considered I paid $700 last year to have my clutch replaced – to hell with the quote! I am gonna do it with the help of a friend.

My question, however, is what do I need to buy besides the belts. My friend mentioned that for his Cayman he had to add a harness bar. Do I need the same for my Boxster? If so what and where do I get it?

I think it’s worth mentioning that I currently have Kirkey seats and I seat very high, but enough to clear the holes in the backrest of the seats.

Has anyone come across a DIY for the install?

All the best,

Gus

Gus - I have a 5-point harness in my 04 986S with Sparco Evo seats.

I used Brey-Krause hardware to attach the lap belts, and a Brey-Krause bar for the anit-sub belt, as well as Brey Krause side mounts for he seats. They make good very good stuff. I did not need a harness bar for the shoulder belts - they pass cleanly through the holes on the seat and loop around the horizontal bar on the roll hoops.

If you are installing a harness for track use, be extra careful about the angles of the shoulder straps - most harness makers will tell you in their literature what the angles should be. If the angle is too acute, the harness cannot work properly - one way it compresses you; the other, it does not hold you down if you are inverted.

Thank you very much, Eric...

Looks like it is not a very hard DIY!

Would you have the part numbers for the Bray-Krause stuff?

Did you order them online?

All the best,

It was not hard. Just pay attention to the order the factory has installed the washers and bearings on door side attachment point - I think I reused some of those. You may also want to remove the seat to install the tunnel side attachment point - to have room to get your hands and a wrench in there. I assume the Kirkey has a mount point on the seat for the tunnel side.

And you may want to leave the factory belt installed and plug it in under the seat so the airbag continues to operate - or at least turn off the airbag light), assuming your model works the same as my '04. I used a zip tie to strap the belt receptacle that came off the factory seat to the floor, and then plugged in the belt (with the electronics attached to the air bag controller harness, of course). You may figure out a cleaner way to do it, but it works for me as aesthetics are not a priority on this dedicated track car.

I used R-9004 on the tunnel side - you may need R-9001 depending on the location of your attachment point on the tunnel side - for me, with the Sparco Evos, it was on the seat in a place that did not require the extra long ones.

On the door side, it was R-9003.

For the anti-sub belt, it was R-9030, but, I think R-9030 only works with the BK side mounts. So this is probably going to be more of a challenge for you. You might have to find a generic anti sub bar that will mount to the factory sliders, or to whatever you have for mounting the Kirkey.

bkauto.com is a pretty clear website - check it out.

I ordered online from the cheapest vendor I could find. Don't remember who now, but I just googled and researched till I found the best deal.
