I have some 20mm spacers. I had a different use, but stock lugs aren't long enough for the rim and 20mm spacers. you will have to cut your own from longer ones. My wheels with 20mm had a slight wobble, changed to 15mm and were fine. More thread entered the hub. Becareful not to go to far because you will hit the ebrake inside the hub. You can put your lugs on, and jack up the rear and spin the wheels if not clicking or rubbing then your good. My whole purpose was to use stock lugs, you may want to find the clearance first and then just cut your lugs to fit.
