    Roll Bar Question For Convertibles

    Is a 4 point bar good enough for 11.5 runs? Just want something I can take out the back seats and bolt in.

    Does anyone know a place to get a pre-fab 4 point for the F-Body Convertibles? Not sure if the SS and WS6 can interchange on the bars or not.

    So to recap:
    What's the minimum bar required for 11.5
    And who's has the best deal on one.

    I do have a line feed, so I can make one I guess. But I'm a crappy welder. It seems like welding must require some artistic talent of some kind. I can make things stick together, but even a grinder aint good enough to make it pretty.

    Well, I did a little research and found:

    You can run as quick as 10.00 (with unaltered firewall and floors) with either a 6-point or 5-point (door bar on drivers side). NHRA requires a roll bar at 11.99 (13.99 Convertible).

    Found a site that sells various point bar systems as well:
    http://www.wolferacecraft.com/detail.aspx?ID=240

    But, I'm still confused. If I put a 4 point bar without the door bar, does that mean I can go 11.99? If I want to go faster, I would need to add a welded door bar. Am I reading that correctly?. I'm sure there is some rule book wizards out there. I do not want to put in a door bar.

    That must have been an old rule book you found. The rules have changed since early last year.
    You are now required to have a roll bar at 11.49 or quicker for a hardtop and 13.49 or quicker for a convertable.
