Hey guys sorry if this is a repost but during the picnic a couple of us were wondering what the rules are regarding convertibles at the drag strip...do they all need a roll bar or is it like most things in NHRA where its only once you have hit a certain time? Is there anything else I would need to run a 01 cobra vert with 4.10s and a short throw and drag radials? I know each track is different so please specify which track your referring to.(I didnt feel like paying for the NHRA rule book so thank you in advance)
