RC,
Hi,
A good chassis/fabrication shop will be able to fabricate a 6 point rollbar, 3" above your head. Good to 11.00 at NHRA tracks.
You didn't say if you had a solid or independent rear in the car, anything faster needs a 9" solid rear end.The chassis shop will have to do alot of reworking to make your rear suspension hook up. Faster than 11 flat needs a full 10 point rollcage or a roadster cage welded in plus all the other safety gear, pick up a NHRA rulebook.
Anything faster than 11 flat in a cobra[ short wheelbase] is just asking for trouble , you should be thinking of another longer wheelbase car to race for stability and weight transfer.
Good Luck.
Perry.
