IMHO, the center bars will be too close to your head, as well as the passenger's head. Without a helmet, that is a head injury or death just waiting for the right circumstances to occur.
If, you & your passenger always wear full 5/6 point harnesses ... tight ... you need any roll bar tubes to be a minimum of 6" away without a helmet. The exceptions to this would be:
* Where the headrest prevents your head from going back towards the main hoop
* If the seat was a full containment race seat, designed to limit side to side head movement.
That looks extremely dangerous for a street car. Pick which is more important. Race car or street car? Like most things in life, you can't have it all!
Thanks guys. Ron, I was hoping for your input. I'll put a tape measure to it this weekend using stock seats. The Corbeaus are LG1s and so they are not full containment.
The front hoop and connecting bars seemed like a great idea until I saw it after the fact. I want safety to be the primary factor and the car will not face serious track time. I wanted to build something that would be along the lines of the Optima Challenge cars. The fact of the matter is that the front hoop is going to cause me to spend thousands of dollars on a hand built dash because I can't get a stock one back in there. So there is sort of a silver lining to this cloud if I do need to take this out.
