E30 Zone

Hi, my friend is about to lower his E30 2-dr 325i by either 40mm or 60mm. He has recently fitted a set of 17" Alpina replicas with 205/40's on the front and 215/40's on the rear. Does anybody know if 40mm or 60mm lowering springs will fit without the requirement for any modifications to the wheelarches, etc? Thanks.

Various threads on this, here's one example (do ignore all the trolling, there is actually some decent info hidden in between the crap!): https://www.e30zone.net/modules.php?nam ... c&t=229613

That's great, cheers. I shall have a look when i get home from work.
