Hello and thanks in advance for any help. I have been reading and rereading the rule book to set up a MGB to run e modified, please excuse any misinterpretations of the rules or any differences in terms that I use. I have done lots of fabrication but have never done a roll cage and that is one of the next projects coming up.
Reading through the rule book I plan to use 1.75 inch tubing, my biggest questions come from the bracing. The passenger compartment is likely similar to a Miata and I noticed the rule book suggests that braces go to the back of the car whenever possible. I plan to do something like what I perceive to be a 6 point cage with two braces to the front and two to the rear. I notice from many pictures that the forward braces on many rollbars are quite high, above the door on cars similar to mine and was wondering why that is. I noted that at least one brace has to be in the top third of the hoop and at least 30 degrees from vertical. Is this a packaging issue and if so, other than padding, what can I do to make these braces safe since they would likely go right next to my helmet? I have a full face helmet and got nice racing seats with lateral support and 5 point racing harnesses already.
Also, this will be a two driver car also piloted by my soon to be wife, she is shorter than me so I assume that I should set up the bar to be two inches above my helmet and six inches behind the seat at the setting I will use. Would that be the safest option for both of us.
