I sent an email to the Tech Committee and have not received a reply so I am asking for your thoughts on the roll cage. I had a epiphany, with out drinking by the way, about making a dual hoop cage for the coupe. I am about to commit to metal and would not want to make a technical foopah. Yes, we sometimes have to work outside and that is not an oak tree in the background, but it is a shade tree.
We have placed the race seat in the car and added more tubes to the mockup since the photos to find out how easy it will be to exit. Not easy at all! Ejector seat needed and the roof flap will need to be a bit larger! Removable steering wheel added to the list. Grab handles added to the list. Reduce the size of breakfast and dinner added to the list. My wife has started an exercise routine for me, bless her!
This has been very interesting to go from the thought of "there is going to be plenty of room even though it's a medium sized interior, to, Wow! this is going to be tighter than I thought for some components. Mind you it's not a streamliner however once you start to check elbow and head room with the added bars the interior shrinks! Your comments appreciated!

Dear Technical Committee Cars,
Mr. Lee Kennedy and Mr. Alan Fogliadini, my name on Landracing.com is Geo and I have been reading the posts for about a year and have read the 2008 rule book some 30 times. I think I am beginning to understand things. However I need your advice on one item as follows for car number 1081 as shown on the entry list for Speed Week 2008.
I am building the roll cage and with the rear hoop well behind the “B” post on my coupe I would like to add another hoop at the “B” post giving us the ability to have head protection and support similar to the streamliner and roadster “funny car type” cage as shown in fig.4 on page 26 of the 2008 rule book. We will also have the forward legs at the “A” post giving six legs to the cage, instead of four legs as shown for a coupe in fig. 1 on page 25. A seventh support will be vertical from the floor near the center of the car to the middle hoop for the inboard head protection attachment point, forward end. And we will have two rearward support braces from the rear hoop to the frame by the rear wheels.
My thoughts are to use the area at the rear of the door opening for added protection without hindering the ability to exit the car. Rather than extending minimally supported arms from the rear hoop to support head side restraints “helmet-retaining strap” I would like to build a box for the head, neck and shoulders that will have the head side restraints “helmet-retaining strap” supported front and rear on the two hoops.
I have attached a drawing of the basic structure and photos of the mockup we are constructing. Please note the factory seat in the photo will be replaced with a metal racing seat allowing the driver to be lower.
Thank you for your work with SCTA-BNI allowing us to safely partake in speed trials.
Best regards,
Geoffrey Green
