Tucked as tight as possible w/o cutting the stock a-pillar is not what I consider to be "the fullest extent". - The way the stock pillars are designed in these cars you could easily cut the back side out and bend the tubing to actually fit into the stock pillar, then weld it to it. The stock trim panel could be set back in place and the cage pipe would be non-existent.

Re: just how much weight can we ACTUALLY get out of our doors?
I just "gutted my doors" so to speak. My doors have the big channel impact bars in them and I cut out some of the extra sheet metal and got 15.6 lbs out of it. Still have some more to do and yes the windows are still functioning perfect. Going to tackle the drivers door tomorrow.

Re: just how much weight can we ACTUALLY get out of our doors?
I was a little afraid of cutting so much out of it but I figured i can weld it back in. To my surprise its very sturdy and actually doesnt clank when you shut the door now.
This door brace is about 6 inches short now but is pretty damn thick.
Sorry the damn pics are so big again.

Re: just how much weight can we ACTUALLY get out of our doors?
Ouch! - x2 to what Zone said though, could have happened at a much less opportune time.
I car I crew for ran over a small glass fuse in the pits one time and cut the tire, they were new too, just one pass on them and picked up the leak somewhere on the return road. - Seriously, a freakin little glass fuse. wtf?

Re: just how much weight can we ACTUALLY get out of our doors?
i've decided to scrap this project. with the amount of work involved for the weight drop, it's just not worth it. i might get a total of 30lbs out of the pair of doors, and now the door is really flimsy. if i was going to make this car a dedicated drag car i might consider it.
My doors weighed 89 lbs with the door panel removed. I removed the power lock mechanisms and a piece of sheet metal that was for the door handle which saved a couple lbs. Not gutting the doors is the biggest ‘street’ sacrifice on my car. IIRC road racers are getting their doors down to 34 lbs each with working hinges or if you go down to skins only gets you 150 lb weight savings but the doors must be bolted to the car. http://www.frrax.com/rrforum/index.php?showtopic=13703

Re: just how much weight can we ACTUALLY get out of our doors?
I dont drive my car that much nowadays it seems, i always pay attention as not to get T boned, so i dont have that big of a chance of getting hit but i am not immune, the 6 point roll bar i want will make up for it pretty good, but i am more worried about getting rearended and the lack of rear bumper causing irreparable damage.

Re: just how much weight can we ACTUALLY get out of our doors?
Yea if you have a roll bar setup then if you get hit from the side the roll bar is far stronger then some cheap little metal braces in the doors that will probably do nothing against a car hitting you anyways. I dont know what I will do if I will gut mine or not. I am just concerned with the flex in the doors and the paint job. I will build a beastly bottom end for my setup soon and just make up the weight difference with some nitrous. Two ways to go faster. Get lighter or make more HP

Re: just how much weight can we ACTUALLY get out of our doors?
Stronger? yeah, maybe, but you need energy absorbtion in a crash = Force x Distance. If you add a door bar that is basically touching your elbow your distance is very short. Even if it is much stronger there isn't much crush zone to absorb energy. I disagree with your statement that the factory beams do nothing in a crash.

Re: just how much weight can we ACTUALLY get out of our doors?
i agree that the crash bars are there for a reason. having them towards the outside of the door means that the on coming car hits it almost immediately, which is going to slow it's momentum down before hitting you. the door bar on my roll bar doubles for an arm rest, it's right in my kidney area when i sit in the seat. alot of this info was what made me scrap the project, atleast till i stop street driving this car on a regular basis.

Full 25.4 cage + harness & associated protective gear = I don't give a fu.......lol. Carbon fiber doors plus lexan windows = less than 15lbs each total weight (less than 10 IIRC).
