thanx guys for all the comments n help I think Im gonna go with the type r style cause it's a little more flashy than the m3 without being too over powering so I can still get a rear window visor
I know this is an old thread, but I just bid on a "2001 -2006 BMW E46 COUPE M3 CARBON FIBER SPOILER" on ebay before I checked to see the dimensions. Looks like I will win the bid. I have a coupe and the deck lid is 47"...the bmW spoiler is 48". OOPS!!!
