Don't worry about the bearings! if you used 22B wheels then that would be the equivilant of using (i think) 18mm spacers!
I use 20mm spacers on my wheels for trackdays, there are bolt on Eibach spacsers,
You can try them on if you like, If you want to call down to me sometime, we can do a pitstop outside my place!
I think they cost me 250
