Mike's absolutely right about the proper amount of
protection-- for a SCCA or SVRA car, or a serious 'canyon
racer'. For the rest of us, roll bars will be, like all
designed products, a compromise. Factor in issues like safety
(could _any_ roll bar have saved Aryton Senna?), convenience
(like can you put up the top? Even on a Mk1? Will it clear a
hard top?), weight, cost and appearance (a full cage doesn't
do much for the car's lines), and each of us would pick
something somewhat different as ""ideal". There's gotta be
some middle ground between a tin-foil "show bar" and a NASCAR
cage, eh?

"I saw Larry's nice chrome roll bar"
Thanks; wish I could take credit for it. No Mk1A or MkII
owner would have a use for the "folding" feature, but at
least I can put up the top on the Garage Queen w/out
unbolting the "boot doors". The assembly is pretty _stout_;
IMHO, I have some protection in case of a moderate-speed mishap.
"Anyone do the double hoop?"
Like the ones I've seen on Miatas and BMW Z3's? Neat idea,
and unlike the one shown at
http://www.corpdemo.com/tiger/pictures/atbraden.jpg, it would
leave a clearer view out the rearview mirror (another design
compromise). And, better yet, Jeff wrote:
"Tiger Technologies isin the process of prototyping and costing
out a double hoop roll bar for
Mark 1As and Mark 2s (Sorry, Mark 1 owners). "
Bravo! BTW, considering attachment points for shoulders belts?
" The piece will be available in
either chrome or powdercoat black and will include a
longitudinal bolt on
bar running from the center of the hoop to a chassis point
on the far right
corner of the passenger footwell. "
Will the bar attach to the left or right hoop? Having trouble
visualizing...

Not only in rear-enders; I drive with the seat
all-the-way-back, and if hard acceleration pulls my head
back, SMACK! The pivot bolts for the Y-shaped rear strut are
fortunately directly in line with the centerlines of the
seats; I'm thinking that some fabricated clevis-type brackets
put there would allow installing some little round pads (I
have some red leather left over) to act as head rests.
However, I think the racer-types will tell you that in a
rollover, your head goes all over the place, so padding the
whole bar is safer, even if it looks barfulous. And I don't
have that much leather.

What can one say, but OH SHT? Could you share the name
brand with us?
BTW, would engineers driving Tigers need extra-tall roll bars
to clear their heads? :-)
