I don't know if it stiffens the body more than FM rails, but geometry is on the door-bar's side. A few posts above and you'll find this answer.

Now I need to weld little tabs on my 1.6 rear subframe so I can attach the beatrush bar. I'm still toying with the idea of strengthening the PPF too because I know that poor little guy if not twisting, will eventually fail from fatigue.

So is there anyone out there that still doubts the effectiveness of the door bar approach?
Forget about the safety arguement; even if it is an issue, my Momo buckets are taking care of that.

Already answered. Yes. The only reason I know of to get rails instead of door bars, especially if you already have a roll bar, is that some do not like having door bars in the cab for whatever reason. There is a long discussion about it at miata.net. Otherwise, considering the cost/stiffness ratio and the weight/stiffness ratio, the door bar is better IMO.

I already had an HD roll bar in and a triangle shock tower brace. The rails really didn't make a noticeable difference in driving feel. There is a difference when jacking the car up so I know they work but it wasn't significant enough for me to tell on the road. The strut brace was an bigger change.
Of course my wife accuses me of being insensitive. I guess this could apply to my driving too.

I had no clue that a 15-point cage was more rigid than door bars. Thanks for the enlightenment. lol

Damn you trendy ******' bastards.
When I had expendable cash to spend on chassis stiffening everyone said frame rails were the way to go, and some of ya'll even talked me OUT of door bars.
Don't get me wrong, I love my frame rails...but now I'm gonna HAVE to get door bars as well. I'm going to stop listening to you guys before end up broke (and divorced).
