Re: Roll Cage+convertible (Gutted Hatch)
A 6-point roll bar is mandatory in a convertible for ET's from 13.49 to 11.00, and a cage is required once you go 10.99 or trap 135 mph or faster.
From the NHRA sport compact rulebook:
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote »</TD></TR><TR><TD CLASS="quote">
ROLL BAR:
Roll bar mandatory in all cars (including T-tops) running 11.00 to
11.49 (7.00 to 7.35 eighth-mile) and in convertibles running 11.00
to 13.49 (7.00 to 8.25 eighth-mile). See General Regulations 4:10,
10:6.
ROLL CAGE:
Roll cage mandatory in cars running 10.99 or quicker or any car
exceeding 135 mph. Cars with unaltered firewall, floor, and body
(from firewall rearward, wheeltubs permitted), running between
10.00 and 10.99, roll bar permitted in place of roll cage. Cars
running 9.99 or quicker must have chassis inspected every three
years by NHRA and have a serialized sticker affixed to cage before
participation. See General Regulations 4:11.</TD></TR></TABLE>
