Just taking a poll. If you read the GCR to the letter of the law, you are allowed to run 1.5x.095 tubing on an ITA RX7, but the RX7 just squeeks by. If it were classed with a weight even 10lbs higher it would require 1.75x.095 or 1.5"x.125 tubing. So if a car like the RX7 were to be classed in ITB at a higher weight it would change the tubing requirement - and the ITAC is hesitant to create this situation.

My question: What size tubing are you running on your RX7? (would it meet the heavier requirement anyway)

Thanks!!
