    Default Steering box differences

    Are there any differences on the steering boxes on the different models??
    I know some has servotronic, I was thinking that maybe the M5 has a "lower ratio" shorter distance from outer position to outer position??

    Yeah, I read somewhere that the M5 had quicker steering than other models. Is this true?

    Anyone know the specifics and exact numbers? Experience?

    The servotronic was an optional extra on all e34's, according to the 1990 options list.

    The 525ix (AWD) has rack & pinion steering. (Just to confuse the issue)

    What is "Servotronic" anyway? What does it do?

    If I have a non-Servotronic 530 V8 car, can I swap in the steering box from a '91 M5? Is it as simple as swapping in the new steering box?

    Sounds like a nightmare to me - different hoses, etc. I've got both a 535 and an M5. The boxes are different. The M5 boxes are fairly hard to come by - and good luck getting renovation parts.

    There are a myriad of differences between the two cars that give them their different characters. To try to make the 535 more like the M5 is going to take a lot more than a steering box - and cost a lot more than buying an M5.

    Springs, roll bars, dampers .......etc.

    Only the ix, as far as I know.
    E36 6 cylinder and E39 6 cylinder cars have rack & pinion AFAIK, E39 V8s do not. I don't know about any others.
