ok based on your new calculations, 20mm up front and 12mm in the back will put both rims 1mm behind the fender. If you want a little more poke I would say 25mm up front(which I don't know if they make that) (which will put you 4mm pass the fender) and 20mm spacers in the rear (will put you 7mm pass the fender)
also how are you BC coils? How low do they go? And do you have to adjust the preload for them to go real low?
