i'm too lazy to link it, but there are vogtland springs on ebay for e90 for like $150 shipped if i recall!
i was going to consider them but i ended up buying Hunters Hartge springs, which i have yet to install.
Mastarge has rated them good, and i have heard other good things about them.
just a heads up to the fellas on here. if you end up buying them, you can paypal my commission to
tl_boy@e90post.com. $20 should do.
