Brilliant idea on lines of Americas cup technology

I sent some photos to you but you may not have got em!

Anyway I have had a brain wave - I think! my car is similar to the ERA in chassis and body design, is probably heavy enough in chassis material and in my opinion my chassis needs stiffening for circuit use, hence this idea which is at the about clutch area or firewall I am required to fit a strap of metal bolted to chassis 100mm wide X 3mm thick going around tunnel, supposedly in case of engine going backwards in a crash.

What I am considering is to attach forward tubing to as far forward as possible where my chassis kicks up to front suspension, from the tunnel strap, bond in the tunnel at the upper corners Carbon fibre angle pieces 10mm thick by 75mm wide, going full length of tunnel, and have three similar width vertical hoops straps going down to the chassis X bracing behind transmission area and all this attached to tubing at rear, diff end of chassis.

If you look side on the design this provides an upper structure going up from front susp to about 16" at firewall strap and down tunnel to diff 7" the only thing I am not certain on is the fibreglass tunnel which is only about 3mm thick at most, but carbon is light. I considered metal tubing but as the tunnel is narrower than the wide chassis 4X3's at almost 27" that would be heavy and impractical.

Having said all that I hope its stronger than our Americas Cup boat
