2 piece rotors for W220 S55
 

Anyone know of a source for two piece (floating) rotors for a 2004 S55? I know EVO Sport and others have offerings for the E55 but they apprantly won't fit an S.[>:]

Also, on the subject of unsprung weight, can anyone tell me the three or four lightest 18" and 19" inch wheels on the market for these cars? (Don't want those soft Kleemans!):) Cost is an issue eventually but low weight with strength are the highest priority so I ain't expecting cheap.
