I'm looking for ideas or suggestions to relocate the harness bar upward to better work with my HANS device. I bought a new seat that is more upright than the original. As a result, it looks like my shoulder belts are coming in at a bad angle. I'd like to add a bar to the cage to relocate where I mount the shoulder harnesses and try and keep me from getting compressed. Does anyone have any photos of something similar, or suggestions? I saw something similar months ago but I don't remember where it was.

 

Thanks

just weld tabs on the current bar.  get some 1.5 X 3 inch tube and cut diagonally on the short side then hole saw the wide end and weld to bar.

I can't seem to post a pic from my phone. I have access to a cool guy with a pipe bender. So he bent a length of 1.5" DOM into an upside down U and welded it to my main hoop cross bar.

What are the specs on that bar? Do you have any photos of it in place?

I've been trying to visualize this for about a week now. I can't see it.

I can take a pic but I won't see the car until on the way to Hallett.

 

Let me try and explain more verbosely.

Step 1. get some rectangular tube 1.5’’ X 3”  about 4” long

Step 2 cut this tube diagonally alone the 1.5” side so that you are left with 2 channels of the 3” with the short sides tapering from the 0” to 1.5”.

Step 3 notch the 1.5” sides with hole saw the size of your current harness bar (this is where you will weld to harness bar).

Step 4 drill holes near the 0” end on the 3” side and use belt mounting eyebolt and belt clip on end to attach belt.

Step 5 weld these 2 mounting tab to the harness bar at an angle that gives to the height you need.
