    Hey guys. As stated in the title i have a broken spring on my car, bmw want silly money for a set of springs, but nowhere else seems to list them for the m-tech model, i have tried a standard set but it obviously sits too high. Does anyone know of a possible replacement that would keep the ride height & stiffness correct? I.e how similar are the M3 REAR springs in comparison to the m-tech stuff? Many thanks.

    IIRC the M-tech suspension sits approx 15mm lower than the standard ride height.

    In order to keep the same ride height etc then you will need to replace both rears from BMW. However why don't you purchase a set of Eibach lowering springs and benefit an upgrade at the same time. I'm sure four of their springs will be similar to a pair from BMW???

    Cheers!

    Well bmw want £153 + vat for 1 spring, i dont like replacing single components when it comes to suspension, so were talking close to £350 for a set, so a set of aftermarket springs is much cheaper, like half the price! Ive been looking at various springs, at various lowering amounts. In regards to m-tech sitting approx 15mm lower than standard height, is that all round? So if i were to buy a kit, this one for example:http://www.europerformance.co.uk/pag...roduct=3771076 my car would then sit approx 15mm lower than it is now? As i would guess most of the lowering kits are rated on standard factory springs and not m-tech? I dont want to lower the car by crazy amounts!

    Been looking at a few more options, it seems alot of lowering kits drop the rear more than the front, are the rears on standard cars lower to start with? There seems to be alot of confusing information i.e:
    http://www.europerformance.co.uk/pag...product=437400
    and
    http://www.potn.co.uk/p1358137.htm.
    Both the same product code/numbers, one says exc. m-tech, the other inc. m-tech?!!
    Anyone got any recommendations?

    I had a rear spring go weak on my e46 coupe and like you say 1 spring was £77 + the dreaded so talking 154 for 2 rear springs . I myself upgraded to a set of Eibach pro springs which lowered the coupe 20mm upfront and 15mm out back and i paid £99 for the whole set. I got them from here, they do E36 kits depends how low you want to go http://www.espdesign.co.uk/Suspensio...647/index.html. With regards to the mtech bit, my coupe had mtech suspension which obviously meant it sat lower than normal susension. It just meant that the eibach springs didnt lower the car as much as it would of done if fitted to a car using normal springs. I found no problem using the eibach springs as the pro kits are designed to be used with standard shocks and found the ride to be pretty much the same. Hope this helps outs

    Most manufacturers do a lower FRONT than REAR. This is because if you look at the car side on you will notice the rear is cut differently and appears lower anyway.

    IIRC manufacturers base lowering heights on that of the base model so if you were to buy a set of 40mm springs for your car then it would only lower yours by an additional 25mm

    There are different levels of M-Tech. Some have long anti-roll bar links that secure to the shocks on the front. I believe this may be the one that is excluded?? Best thing to do is check to see which type of links you have and give the seller a call to confirm that they will fit.

    If unsure of what I am referring to let me know and I will get a picture whilst i'm under my car and freezing my nuts off tomorrow

    Just a quickie, would rear m-tech springs from a 92 318i saloon (had an m-tech upgrade), fit my 99 318is coupe?
