according to the link a above are they referring to just a regular 4pt roller or a 6pt cage? just trying to see how much of a cage i might need for the coupe

6pnt is a roll bar as far as NHRA is concerned. 11.49-10.00 you need a min 5pnt bar(everyone usually just builds a 6pnt). 9.99-8.50 or anything that goes 135mph or faster(regardless of ET) needs an 8pnt cage(meaning the driver is totally in a cage, ie it has a halo).

thanks for the clarification i thought i was reading it correctly in thinking it would need a 6pt
