Now that I've owned a 2dr for a while, every time I get in a 4dr car I bang my ass on the B pillar. I love coupes. :) So much easier to get in and out of, bigger windows to see out of, not to mention less room for 2-3 backseat drivers we all don't need.

funny, that's one of the reasons my car doesn't even *have* a backseat anymore.

good 40lbs of weight shed, and "oh sorry, got room for me and the girl, that's it" ;)

It's easier to bone in a 4-door. Just my .02

Ok that kills my plan for trading this iC for an iX to build an evo killer, well not actually boost doesn't care how much my curb weight is. But this once against lets me know how much lighter that guys gutted 325is with the rolls bars is than my cabrio.

um just to let you know its about a 200 pound difference and four door cars are alot less stiff. ill let you know the exact weight difference when i get home and look it up.

um...200 pounds you say, huh...

Data from 1991 model year owners manual, enjoy.

This argument on 4 door E30 being more rigid than the 2 door E30, is it proven???
I always thot that the 2 door E30 is more rigid...

As for the E36, I know it's proven that the 4 door E36 are more rigid than the E36 coupe...

[C ///M]

Exactly what C///M said

the 4-door is more rigid because there's a large strong B pillar that needs to hold up a door. the weight difference isn't much as you would think, because the door on the 2-door is larger & heavier than the ones found on a 4-door, narrowing the expected weight difference a little

sure the 4-door has "an extra pair of holes in the side" like Tangent said, but like i said above, because the doors need something to mount to, a B-pillar was put in place that not only holds the doors up but contributes to structural rigidity

also, the doors are not much different than the side panneling thats behind the large door of a 2-door... so there's not much extra weight there, either... and the glass?... well, a 2-door has glass behind the doors, too.... just no motor & track to move it up & down.

and the handle mechanism doesn't weigh much either

basically at first i can see how alot of guys would think that a 4-door would be significanly heavier than a 2-door... but the more you think about it, the more common sense will prevail & tell you that yes, there is definitely a weight difference, just not quite as much as you would think


As for weight distribution, i'm gonna venture a guess & say that the difference would be very negligible, but the 4-door would probably have a slight edge if there was any difference at all

Wow...read much? Yes it is, as you say it, proven. It's physics.

Where in the hell did you dig this thread up from?

[BS87]

I dont know, but it reminds me how much of a pig my cabrio is.

[LowR3V'in]

christophbmw is a funny guy.

[e30 gangsta]

im sorry im not all knowing about bmw's and e30's but im trying 2 learn sorry if i make a dumb post and all the members flame me....

[e30 gangsta]

also i just think when a 4 door car does something that is domniated by 2 door cars.... it awesome and makes a statement.

[clutterbucker]

Boning in a four door I can see being easier. Boning in ANY E30 I can't see at all. You people must be short...I'm 6'0 157lbs and would NEVER being able to bang in my car. Lucky you.

Wait...why would you ever want to have sex ina car to begin with....it sucks.
