Single or Double Roll Bar?

I am looking to get a roll bar for a Mazda Miata possibly from Boss Frog:
http://www.gomiata.com/bofrroba.html

I need to make an intelligent choice between the single and the double.
My main concern is functionality and safety not looks, and price is no
object. I know nothing about roll bars. Comments on whether single or
double is preferable and why would be much appreciated. Comments on who
makes good ones would also be appreciated.

No double-hoop bar is SCCA approved for Solo I competition. Some
single-hoop bars are. If you're heading for a track day, "meets
specifications" may or may not be the same as "approved."

If you're taller than about 5'8", there's an inverse relationship
between protection and head clearance that you'll have to resolve
according to your own comfort level. A bar that sits far enough rearward
to clear a taller person's head will have to be shorter to fit under the
top. That said, no rollbar that fits under the Miata top is high enough
to keep a tall driver's head from hitting the ground, though any of them
should improve the odds of surviving a rollover.

You also need to evaluate the risk of rollover against the risk of the
bar clobbering you in a rear-ender. Rollbars are designed to be used
with helmets, and no amount or type of bar padding is a substitute for
Snell-approved head protection.

The most popular approved Miata rollbars are variants of the Hard Dog
Hard Core. See http://bethania-garage.com/why.htm

Many bars limit seat travel--both slide and tilt--for driver and/or
passenger. You really need to sit in cars with various bars installed.
Most are intrusive to some degree, and you'll have to decide for
yourself how much discomfort you can tolerate. Unless you're vertically
challenged, of course.

I just ordered a D2 from Bethany Garage the other day. They are in stock
and mine is supposed to ship this Monday.

I don't race, so getting the double hoop was not an issue for me. I'm also
not very tall, so the height of the the double hoop was not an issue. And,
I just like the way they look (but would never settle for a style bar).

So, if you're looking for added safety for everyday driving, then any of the
Boss Frogs, Hard Dogs or Brainstorms should cover you -- just get what
appeals to you. If you're racing, you really need to pay attention to specs
as mentioned by others.

Have fun...

I am 6'3", do you know if there are any roll bars suitable for my height? I
won't be racing, just using on the road.

Since you probably won't want to adjust the seat other than all the way
back and reclined into the carpet, you may be happiest with one of the
bars that mounts a few inches farther rearward, such as the Hard Dog
Hard Top (single hoop) or Deuce (double hoop).

I'm tempted by the Deuce, but SWMBO doesn't like rollbars of any
sort--they make her feel enclosed, and spoil the roadster feeling.

OK, please flesh-out SWMBO.

She Who Must Be Obeyed.

Expression popularized by John Mortimer in his excellent series of
books, stories and the PBS series "Rumpole of the Bailey" about
Horace Rumpole. Rumpole was a barrister who always referred to his
wife Hilda as "She Who Must Be Obeyed"

The expression was probably started by H. Rider Haggard in his novel
"She". Ayesha was referred to by her subjects as She Who Must Be
Obeyed.

If you're married the term is easily understood...

I've got a Deuce and couldn't be happier with it.

Wha? Does she demand that the doors be removed as well?

You don't even know the Deuce is there 95% of the time. It's
barely visible in the rear-view mirror, and it certainly isn't
visible in my peripheral vision. The Duece is a lot less
obtrusive than a high back bucket seat or a headrest.

Grant, my lad, one of these days you will be married. Then your eyes
will be opened (if not blackened) and all will become clear. In
marriage, as in war, the wise man chooses his battles with care.
