Buying replacement coil springs

[E36 Daz]

Just discovered a broken rear spring so I intend replacing all 4.

The car has lowered Eibachs on it and I want to go back to standard ride height.

Do all 330 m-sport coupes have m-tech suspension ?

Is there a difference between m-tech and non m-tech springs and if so how do I tell which I need ?

If it helps the car has Sachs 2282459/60 front struts and Bilsteins on the rear

Cheers

Edit : looking at the Eibach site,my car has the red springs which are more lowered than the black ones they also do so I think I'll just order a set of the black ones

haha so did you order them?! I can’t remember where but the official ride heights and how to measure them aren’t that hard to find on Google.

Can't measure the ride height as the car is on a ramp minus it's rear axle lol

fair enough, the eibach kit is great value for money and won’t be too far away from standard height. might be worth doing the front struts while you’re at it, those sachs could be the original.

Eibach Pro Kit black springs are as near as damn it the same height as standard M-Sport springs. I'm running Eibach springs and Bilstein B4 shocks as replacements for the tired M-Sport standard suspension and the ride height is the same.

I've ordered the black kit from Demon Tweeks on Ebay,£30 cheaper than direct from Eibach !

And in more good news,no cracks in my floor
