I second that Patrick, most coilover springs are 55mm or 60mm inner diameter.
H&R's you have fit oem struts set up only but you could adjust them by using thinner spring pads and e90 (?) Top hats.
JOM's use a dual size spring, 55 or 60 (?) Lower and oem hat size on top, adjuster replace nut that holds shock in strut.
Heres pic of 55mm and gc c/c plate... http://www.bimmerfest.com/forums/album.php?albumid=7557
And lower side can be seen here... http://www.bimmerfest.com/forums/album.php?albumid=7028
Dont have pics of Joms but look in their group buy for examples.
