As in a bottom bracket spacer, to be fitted between bb flange and face of bb shell?
6.5mm seems like a hell of a size for a bb spacer. Then again, I suppose you put 2 of those smaller ones (must be a couple mm) on one side of the mtb bbs.
6.5mm also seems to me like a lot of adjustment to be trying to make in the bb/axle area. I'd probably prefer to make that kind of adjustment by shifting the chainring from one side of the spider to the other. I guess I could maybe see why they've gone down that route though and I dunno if you'd really notice the offset on the cranks, I guess someone at Shimano figured it'd be within the realms of usability.
If you fit the bb with no spacers I presume the nd crank bottoms out on the splines on the axle before preloading the bearing?
If I was building with what you currently have I'd probably scrounge a of a few 2mm spacers from the lbs and see where 2 on the nondrive side got me and be prepared to add one on the driveside and maybe add a thin spacer or two between the cog/freewheel if the chainline needs it?
