What you guys are failing to realise is that when you sit in your driver's seat the suspension will drop more on the driver's side than the passenger side.
BMW in Germany (LHD) designed the car so when the driver is sitting in the driver's seat the car is perfectly level to the ground, ie the suspension is now level. FACT!!!
BMW won't make new tooling for weight balance just for RHD models as it is too small a market compared to LHD cars. BMW did however make thicker spring pads for E36 & E46 RHD model's drivers side suspension to level it out. However I have never seen them on any customer's cars.
If BMW were so stressed about weight balance on RHD E90's then the battery would be on the left and the fuel tank would be a mirror image of the one posted.

I have never seen a more childish response... Dude, really, you a good person, don't tarnish your rep by following the one bad sheep.
The point - There was a generalization that cars are lop sided due to it having a batter, engine, etc... Its not true, if BMW in Germany design a car with a person in the drivers seat dont you think they would have taking into consideration that an engine,etc will also be in the car?
The solution - The OP needs to take his car so a suspension specialist to check why his car is lop sided. So much so that it failed Roadworthy and we all know the guys doing roadworthy wont give 2 hoots about it usually.
Come on guys, think about what you saying...

honestly this argument is retarded im not wasting any more of my day on it...
Dude - nobody at all asked you to join in this "discussion", or contribute or even bother, you did it by your own will.
so whether you come or go....makes no difference to anyone...

i was simply saying this argument is pointless because there will be no irrefutable proof of anything because bmw wont publish every small alteration they make to their cars why should they?
and i said i was not participating anymore because i dont agree there is not a problem with bmws being lower on one side, but i also dont see the point in digging up the info and posting it up if it will not be considered good enough proof anyway...
I find your comment completely uncalled for :thumbdo:

Exactly. I don't know what the hell is up today but ja.
I apologize If I have been rude or anything but don't get personal. Full stop.
This thread was a discussion on suspension. Not anuses.
And I believe I have provided enough FACTS to show and state the truth to help out a fellow fanatic.

Not how it is larger on the right than on the left. So more fuel, which means it is heavier.
Now look at any BMW with and inline engine, which way is it slanted? It is always to the right (apart from the M1)
Which means more weight to the right as well.
Now in a LHD car (which a BMW is designed to be) the drivers sits on the left, so they have extra weight on the right, this means that with a driver in the left seat it will again shift the centre of mass to the middle of the car.
Now springs are made of metal which for the most part will undergo elastic deformation, unless a certain force threshold is exceeded then it will undergo plastic deformation (which means it won't return back to its original shape), but there is another condition that also give way to plastic deformation and this is a sub-threshold force applied, but over a long time - like the weight of the car on the springs. So over time the springs will tend to sag and the amount of sag will be dependant on the force on them (higher sub-threshold force will result in more sag than a lower one) so the springs on the heavier side will sag more. Now with more weight on the right hand side plus the added weight of the driver the right side will tend to sag more than the left. The older the car is the more pronounced this will be of course.

The car is a demo, registered Oct 2011 E90 with only 7500kms. Does the above still apply?

No i dont think your springs should be sagging yet at all the car is too new...
THIS IS WHAT I HAVE BEEN SAYING THE WHOLE TIME!!! THE CAR WAS DESIGNED FOR LEFT HAND DRIVE!!!!Edwinz said:There is your answer. The right side is lower. Thus meaning if the driver sits in it it will still be more lower then that. So something is wrong.

Sit in the passenger seat and then measure, it will be level!!!!
Sorry for the mud slinging but you guys refuse to listen to reason...............
