wheel spacers for z32 upgrade

i have a s13 with the ‘tear drop’ wheels and im upgrading to z32 30mm brakes in the front but im not sure how big of a spacer i need for the rim to clear the calipers. Does anyone know what size spacer will clear the calipers?
and where can i get spacers made?
oh and one more thing…will it be safe to use washers as spacers to drive to a shop where i can get a real spacer made?

thanks

a 15 mm spacer makes them clear the 7-spokes…

a 15 mm spacer makes them clear the 7-spokes…

for some reason i always thought that 5mm will do the job for those… doesn’t iQuaBob run 5mm spacers with his z32 brakes?

yes 5mm, pavel wins bing loses… game over.

IIRC for the teardrop rims you need 10mm spacers.
