    Alrite guys

    I have been reading through previous threads on the forum about the springs on the E36 M-tech 318is coupe being 15mm shorter than the standard 318is coupe, people have fitted standard springs to their M-tech and it sits to high...

    I am struggling to find a set of lowering spring for my M-tech 318is coupe, when looking for a set of 40mm/60mm springs it excludes the M-tech from all spring manufacturers.

    Is this because if i do purchase a set of 60mm springs for a standard 318is coupe and fit them they will only lower my car 45mm due to the 15mm lower ride height as standard?

    Obviously the manufacturers can get introuble for false advertising if they say lowers 60mm and it only lowers an M-tech by 45mm? So do you think they just say excludes the M-tech for any hassle....

    Surley if a standard set of springs fit the M-tech an upgrade for the standard coupe will?

    I don't know wot does anyone else think?

    Cheers

    If you bought -60mm springs you'd get a 75mm drop as I understand it - if they fit the M shocks, I'm not 100% sure that they do.

    Its the other way around, if you bought 60mm drop springs you'd see approx 45mm drop as most springs are quoted from standard vehicle heights. As yours is M-Tech & approx 10/15mm lower to start with. The fitment is exactly the same as any other spring, so they will fit fine.

    Thats what I thought to start with too...

    The lowering springs for a standard 318i are designed to take into account that extra 15mm of height compared to an M-tech.

    I think you would have to take the 15mm away from the amount the springs lower by when the are fitted to a 318is M-tech which would only make a 45mm drop extra compared to how it sits at the moment, this only makes sense if the ride height is controlled by the springs

    If for example the struts on the M-tech were shorter by 15mm then your right there would be a 75mm drop in comparison to a standard 318i which would be sitting at 60mm.

    Cheers, I will have to try and get hold of a set to try them, I will let you know.

    M-Tech shocks are infact different, valved differently so that they are a little harder, but height wise you wont see a difference.

    So you could fit any spring designed for the 318i to an M-Tech shock, and it would fit/work, albeit with less of a drop than stated.

    On some websites it says 'M-Tech models will lower less' but some just say 'Excl. M-Tech'

    Thats what got me

    Plus side, if the M-Tech shocks are stiffer, is not having too worry as much about ruining the internals like you do with a standard if you drop it past 50mm

    There has to be something about the whole M-Tech susp. setup thats diff. I have just looked at a few sets of coilies..and they also say 'Excl. M-Tech' Well they replace the whole spring/damper...so it has to be something else that is different.
