Style bar and roll bar are separated like this (as such) only on this forum. For example, I would call anything which isn't going to save you in a roll-over a style bar - this would include the ebay bling/style bars and "roll cages" such as BD *struggles into flame proof suit*.
1stly BD roll cage is not a roll Cage. Its a roll bar. Roll cage in my books is something like the hardcore racers have & it surrounds them completely.
2nd Style bars are not only refered to as style bars here, they are referd to that in many other forums.....one being Miata.net.
3rdly style bars are referd to stylebars because they enhance the style of the car they are installed on. they do not enhance the structural rigitety like a roll bar or roll cage.
4thly i dare say both style & roll bar will
help save your head in a roll over .
in my resreach i've never come across a style bar doing the infamous mousetrap. But theoretically if you do a roll over at 180km/h i don't think anything mutch is going to save you, in a car not fitted with rollcage & racing harness
One example is a blue turboed Mx5 in the UK had a style bar fitted & rolled it very badly. At a very high speed but the little exrta strenth gave the guy just enough room to save his head. & he wasn't going slow either. The stylebar was credited with helping to save his life. Another is rodent. Even his softop held up a little bit to give his head that little bit of extra room to stop it being spaltered all over the road. But this doesn't garrantee safety in a roll over.
I don't have a problem with your point of view & i'm not trying to flame you. I just don't agree with you.

so let the discussion begin.
by the way i'm also very happy to be corrected if i've made any false statements. as this is a very dear subject of mine & if i'm wrong I don't mind being constuctively corrected.
