I have a 99 M3 cabrio but one of my greatest displeasures about my car is that it is an automatic. I'd like to get it converted into a manual transmission but I have a few questions.
First, I've seen some 5 speed trannies for sale on ebay that came off of a 328i and the seller advertises it as being compatible with M3s. I'm sure there are plenty of talented mechanics out there that can make things fit on anything but the real question is: Are the trannies that came on 328i's the same that came on M3s in terms of gear ratios and overall performance or should I look for a tranny that came specifically off of an M3?
Second, can someone please list all the parts that are necessary for a full conversion in case I decide to buy them from separate sources as opposed to buying the full package from one seller.
And also, I heard that some parts are better off bought brand new like the clutch. Can you also list which ones are those?
Thanks very much for the help!
