I gathered a couple of sets of M3 springs during the suspension conversion on my 335i that I ultimately can't use with the 335 due to the smaller overall wheel size on the 335i...
Non ZCP M3 Springs
1 pair of X1 front/X2 rear springs. I don't recall the miles, but they are in good shape with no rust. I got this pair originally before I got the EDC struts...
$75 OBO plus shipping
1 extra set of X2 rear springs. These came with my rear subframe.
$50 OBO plus shipping or $25 if you buy the other set of nonZCP springs.
Perhaps these would be useful if someone is cutting a stock set and wants a second try...
Here are the 2 pairs of nonZCP springs, I didn't take a picture of them separately (the white dust on the second rear pair will wipe off, I can do it and take a picture if someone is interested in them):

I did a full front strut/upright and rear suspension conversion of my 335i. I drove it with the X7/X5 springs for a month or so but they rode too high with the smaller 335i tire diameter (it made the rear gap about 3/4" too large even with the ZCP springs due to the much smaller diameter rear tire.
Local pickup in Phoenix, AZ (east valley) is available or I can ship for an added cost.
