I was wondering whether anyone can tell me if the roof on the m5 is a load bearing piece of the body or whether it is simply an aluminum skin like the e46 m3s. Im essentially asking whether the roof piece is removable. (which it is on the e46 m3) I would be very grateful if anyone could answer this question for me. Thanks in advance!

its "removable" - still welded though. I'am replacing mine with a CF roof
anyone instrested? - sign up !
This is interesting... how does it effect the structure? How does the Cf get bonded to the rest of the body? and lastly, how much weight savings?

How much weight can you possibly save if its already aluminium?
would it be worth it?
Is the roof aluminum? BMW seemed to make a big deal over the cf roof on the csl m3, so i thought it was a pretty decent chunk of weight. Not that i'd do this myself.

I remember seeing a show where they were testing the Mitsubishi EVO MR with the aluminum roof and the weight saving over steel was around 12 pounds. The show then taped down thick rubber to simulate the weight of the steel on the roof and compared the handling differnce on a track. The professional driver said he could feel the difference, so maybe it's worth it.
