to run 11.0 its just a plain bar.
to run 10.0 and slower its a 6/8 point rollbar (back bars/door bars/hoop kickers)
to run 8.50 and slower its a cage
to run 8.49 or faster its a 25.x cage
considering how close you are already to 9.99 i would steer you toward an 8.50 cage
we just got a stockpile of tubing in,awaiting the neon.
