20mm

Will 20mm spacers require shaving down studs in order to fit the stock wheels on? I know that 25mm spacers will clear the lugs, and I've seen a couple of people say they needed to shave down their lugs a bit to fit some 15mm spacers on, but I wonder if a 20mm spacer will/won't require shaving...

Practically brand new. Only used for about 200 miles before I removed them and got rims instead. Ichiba v2 Spacers 27mm rears, 20mm fronts Asking $200.
