10mm and 20mm spacers on my winter wheels...
advans, i'm pretty sure you'll need new bolts with very close to 27mm (stock bolt shank length) + (whatever mm spacer width) shank length to be safe, although the c55 and c230 might have different bolts, so i could be wrong. i'd call phil at rad usa direct to be sure (888.rad.bolt). he helped me out with this subject before.
