Which Roll Bar for NASA and SCCA?

[slates]

Hello DFW Folks.

I still have the 2007 NC Miata and want to do some NASA trials out here in San Francisco. I am looking for recommendations on a roll bar that meets both NASA rules and SCCA STR rules.

Thanks for the help!

NASA roll bar rules:

11.4.7
Roll Bars
All open cars should have a roll bar installed to help protect the occupant(s) from injury during a roll-over. The main hoop shall be one continuous piece with smooth Mandrel bends with no evidence of crimping or wall failure. All welds should be of the highest possible quality, with full penetration [Ref15.6.15)]. All cars with roll bars are required to have adequate roll bar padding per CCR section #15.6.4. In cases where the driver’s head may come in contact with the roll bar should the seatback fail, a seatback brace is required in conformance with section #15.6.21. Acceptable roll bars include, but are not limited to, the following:

Hard Dog
AC - Ace
D - Deuce (center-braced model only)
AB - M1 Hard Core
TB – M1 Hard Core Hardtop
9B – M2 Hard Core
NB – M2 Hard Core

Auto Power
Street Roll Bar
Street-Sport Roll Bar
Race Roll Bar

The above roll bars are examples only. NASA does not endorse any brand or model and will not be held liable for any failures of roll bars.
