I have a Brey-Krause R-1029 Harness Mount bar in my 2006 Porsche 997S.

I mounted my GoPro HD Hero cam on the bar, shooting forward between the two seats, using the GoPro Roll Bar Mount Kit ($29.99).

I quickly realized that I had to use several other mounting attachments to get the camera high enough to see out the front windshield. The "spot meter" exposure setting is best for shooting inside-out, but if the camera isn't mounted high enough, it adjusts the exposure for the dashboard, and the outside view is overexposed.



By the time I got the GoPro mounted 8" above the harness bar, there was so much flex in all the plastic pieces that the camera vibrated when buffeted by wind at higher speeds. The video was unusable.

Here's what I came up with. Total cost less than $5...not including paint.

I took a 1 1/2" PVC "T" fitting ($1.60) and used a hacksaw to cut off the lower half of the "T" so it would ride on the harness bar like a saddle. I cut a short piece of 1 1/2" PVC for the neck (about 4") and put a PVC Cap (.83 cents) on top. I used a Dremel tool and some sandpaper to flatten the rounded top of the PVC Cap.



I then affixed a GoPro flat adhesive mount to the top of the PVC Cap. I used two hose clamps to hold the "T" fitting base to the harness bar.



A couple of coats of spray paint, and I've got got the best camera mount in the paddock.



Five bucks. No shaking.

 

Nice!

 

That's pretty smart - might steal this idea down the line.

 

Not the sort of cost saving ingenuity I'd expect to find on the Porsche forum, but I love it!

Thanks for sharing.
