Just out of curiousity, been thinking of which springs would be best for the 5 and also what their drop and spring rates are.
Does anyone know? (limb) Been thinking if we could list them all here (5 specific and 3 specific as well) it would be a helpful guide for those of us who want to add to their suspensions....
please correct me if I'm wrong and feel free to add more(2thumbs)

For ex:
Stock MS3 springs
drop-1.3F,1.4R
rate- 188F, 171R
Progress(MZ3 and MZ5 specific)
drop-1.4F,1.4R
rate-190F,170R
Tein H-tech (MZ3 specific)
drop-1.4F,1.1R
rate- 146F, 224R
Megan Racing (MZ3 specific)
drop-2"F, 1.9"R
rate-250F, 230R
H&R (for MZ3)

Great thread and look forward to the details. Any details on the rate of the stock MZ5 springs as well (for reference)?

I know you are still collecting info but consider putting this in a table format.
Also, be good to collect a list of shock/strut and full coilover kits available.
 
I'm not too good with computers so if someone can make a chart and attach it that would be great.

Couldn't find the stock mz5 spring rates, but found these rates for the mz3 eibachs...

Pro-Kit
(Linear, single rate)
Front = 160#
Rear = 171#

SportLine
(Progressive, Dual rate)
Front = 97# / 280#
Rear = 114# / 303#
__________________

As for some kind of comparison the stock Mz3 spring rates are 150 lbs/in front, 130 lbs/in rear, the 5 should be a little stiffer than that, but can't be for sure til we find the true rates...
 
mz3 components

also found this on the mz3 forums site, since we can't seem to link on here, I pasted...
these are for the MZ3 but since a lot of us here us the 3 parts, hope this helps...
