I don't think anyone fits inside the windshield line on the original. See pic 11, with the blue one behind you. Much like the windscrean on motorcycles and or even F 1 cars, the screan blows the air-stream up over you. The concern is your sitting about 4" above the other driver... smaller frame perhaps, but he is shoulder at door edge, and you are elbow..... his roll hoops are just above head line, your bar, about 6 " below your headline... If your on an installed seat, I'de look at something custom that you could pull lots of that height out. I would also look at a bar that put you under the roll protection, not part of it...
The roll bar has 2 mounting positions...I can raise it 4"; which would be a good idea for the track...and detracts from the look of the car otherwise. I'm a big guy. If you think I stick up a lot in this car, you should see me in a vintage correct Cobra. My chin is even with the top of the windshield in a superformance if I sit up straight; not to mention that I can't drive one without sawsalling out the dash. If my *** was any lower in my car, I'd be through the floor pan. Most guys install visors, and flip them vertically to help buffet the wind. Without a helmet on, the windshield works fine and the bar is about even with the top of my head; still rather low. I should probably raise it some in both "modes". If you go to ClubCobra.Com and look at the photos from the Western States Cobra Bash, you won't find a helmet below a bar except for the Spec Racer cars. Doesn't make it right; just pointing out that there's a conflict between what looks good and what works good. What I have is better than most as far as strength and height goes...but it should be better considering what I intend to do (and have done) with the car.
I've been thinking about the possibility of an external cage of sorts as well...so I can race this car in events that regulate such things. Something bolt-on and external. There's no way to make it look good; but there are ways to get it done and make it easy to R&R without cutting up the body. Probably wise, considering.
Thanks for the pics Matt, I really like some of those shots and hope Larry will be at future events.
