In the interests of shared knowledge Mr Donut, give it a go & post a piccie.
When I did my first conversion I just used what was to hand at the time. I'm sure there are plenty of alternatives that'll work just as well, if not better. As Doc says, a good set of standard drums will do the job, so it really is just down to looks. I just think discs look tidier & sportier. If we can compile a list of calipers, carriers & discs that'll hang together we'll post it in the Motors, 3 wheels section of the main site.
