The spacers should come with the BB. I just got a raceface BB that has the same instructions and it came with 3 of them spacers.

On my T1 you only can use one spacer on non drive side if you want a 42.5 chainline. Velodrome q-factor is not a big deal on the non drive side. In summation, you should not use the spacers at all for the BB, just the thin 1mm spacers on the non drive side (possibly two) that will ensure no drag and no excess play after the single sided arm bolt is bottomed out.
