This may be a stupid question, but

Do you know if 03's had the rear leveling system? If so how can you tell if you have it? I am getting ready to get the eibach pro kit for my 03 745li and want to make sure I do not have it.

Just look inside your rear wheelwells. If you see coil springs, then you dont have the self leveling suspension.

Some people say that when you lower the front, the rears will automatically adjust to the height of the front. Can anyone confirm this?

He actually is a customer of mine (WALD kit) and he did have one of the first ACS kits with the springs and module. I'm not even sure if they still make that kit. I know its pricey (well alot pricer than 300 bucks for just eibach springs)

The AC Schnit kit is about $700. It includes front springs and software to lower the rear. The software has to be loaded at the bmw dealership. AC Schnit gave me the lowering figure in mm and I forgot what it is --- but I remember looking it up and it was a modest 1.0" drop only.

If you put the car on the rack, you can see that there are one lever on each side of the suspension which is the ride height leveler arm. The position of the arm relative to the supension links "tells" the computer the height.

Just by looking at this setup, I think you can "trick" the system by changing the length of the leveler arm. If I'm picturing it correctly, I believe you can shorten the length to trick the computer into lowering the rear more.

The arm is made of hi strength plastic (i think). THe part # is 37146752797, retails for about $5, you'll need two (1 for each side).

It's worth a try. If all fails, just put your stock arms back. The swap shouldn't take you more than 30 minutes.

whats the quickest/easiest way to determine if i have springs or air suspension in the rear?

and... why are some air and some spring? is it due to certain years?

Just look from the rear-wheel well.
If you don't see a spring, then you have the air-suspension.
The air-suspension is an option, its part of the adaptive ride package. I think it's a nice option but requires more work if you want to modify the suspension.
