Roll Bar in a Convertible Question

Sean Haning · 02-19-2009, 12:10 PM

Can anyone tell me why in the NHRA Rulebook about roll bars it says in the E.T. section "in convertibles running11.00(*7.00) to13.49(*8.25)..." and in the STK section it says, "Mandatory in AA/S through M/S, AA/SA through M/SA, in all convertibles..."

I don't understand the inconsistency, am I missing something?

I don't think you're missing anything necessarily, Sean. IIRC, used to be E.T. convertibles 11.00 to 13.99 needed rollbars. 10.99 and quicker needed cage, just like hardtops, with some exceptions for hardtops with unaltered firewall/ floorpans. Now it's 11.49 for rollbars in E.T. instead of the old 11.99/ quicker. I can't think of another example where they've back-tracked on a safety requirement.

As far as requiring rollbars down to M/S it probably goes hand in hand with the jacket/pants thing.

Personally, I don't think I'd want to race a convertible without a rollCAGE. JMHO

I can understand that. I have a Shadow convertible that is somewhat of a play toy and after seeing Jimmy Malones car in ND a while ago It started the wheels spinning. I remember reading the ET portion and knowing at mid to low 14's my car was legal without one. Then I read the stock rules and saw that about all convertibles must have bars and wondered why NHRA did that. Thanks for the reply.

Why do Art and I running SS/GS (14.30 index) have to have a roll bar, jacket, pants and trans shield - because it is easier for them to police if everyone has the same rules in same class AND the car in the other lane that is sliding through the lights next too you could be going 150mph. The AA car next to you takes you out in the lights you'll know why you have a roll bar/cage
