those will fit perfectly.
dadoke has the exact same setup on his 313's.
recommend either...
frt 235/35r19 - you'll need to modify the front liner to prevent rubbing
rear 265/30r19 - no rubbing issues
or
frt 225/35r19 - OE size for e9x ZSP (dadoke is using this setup)
rear 255/30r19 - OE size for e9x ZSP (dadoke is using this setup)
i think
misterawa is using the OE tire sizes as well, but he has different offsets.
i absolutely love those wheels.
if i ever go to a bbk, i'll be looking into those.
