    OEM springs purchased from BMW with the vin
    Springs have been confirmed to be correct

    Fitted but the car is sitting around 2" higher than it should. I have driven it across some bumps etc and let it sit for a week but still 2" too high. It looks like a monster truck

    Any ideas? The guy who fitted them said he put it back as it came a part but agreed it looks high?

    Is there something within the fitting of the front springs that can cause these issues?

    Thanks in advance

    There is nothing to adjust height wise on stock shocks.

    Is the physical length of the spring the same?

    It’s either that or the springrate is too high. Can’t think of anything else that would make it sit higher.

    Are higher spring perches available?

    Have you got pictures?
    Was the springs taken off lowering springs?
    Do the new springs have a green dot on them?
    Did you fit new top mounts at the same time?

    I'm sure I've read of somebody else with the same problem, unfortunately I can't remember the cure.

    You're probably going to have to take the shock stacks out and apart to inspect how they're built. They're very sensitive to having everything installed in the correct order and the correct way up. But 2" is a lot! Top spring plate upside down?

    I used these two diagrams to (re)build mine and everything came out fine.

    Cheers all

    Springs looked identical to what came out of her

    All 4 (old and new) had red paint on each spring
    All standard OEM BMW springs and sat at a normal ride height to me.

    I do have a photo but noway to host it anymore

    I am tempted to just chuck it into my specialist and get him to strip down and reassemble.

    It did not have new top mounts etc, just the springs

    Thanks

    Can't see how you could get it wrong, it's got to be either the upper spring cup is upside down or the springs have been made wrong, I can't see anything else making more than a few mm difference here or there.

    3.0 upper hats on an evo spring would make it sit high as the diameter is wrong

    Cheers, the only thing that changed was the springs. I checked with BMW who confirmed the part was correct, same markings as the ones that came off.
    I wonder if something is the wrong way round, both sides the same.

    Hope it was not the springs though, only set left in the UK apparently

    i doubt you could fit 3.0 springs to an evo. evo springs are cone shaped hence a smaller top hat, but if for some reason someone had fitted a 3.0 upper previously then it would sit high as the evo spring will not pass over the body of the top hat, should be obvious by eye.
