There are ranges in terms of spacer width that will not work safely front and rear. For the rear, you can run 1-3mm hubcentric spacers, but then you would have to jump to 10mm spacers, unless you find hubcentric spacers between 4-9mm wide with a wheelcentric lip of 66.56mm, which I have yet to see in the past 2 decades. For the front, I've never tried 1-3mm spacers, but you might be able to get away with it as with the rear. After that, again you have to jump to a 10mm or above with the type of spacer crewchiefpro linked to. Of course you would have to buy appropriate length lugbolts to match the increased width of the spacers.
You would have to provide more info as to your setup if you're hoping anyone can provide recommendations on what would work/look good/not rub, etc. Your wheel/tire size/suspension setup will determine alot.

imo, you are better off using cellotape, one end stuck top of wheel arch, bottom end has a weight like pen taped on it, then start your measuring, gravity is honest. i have et64 brabus rims, lots of positive offset, so used 1.5 and 2" spacers front and rear to get it looking like this
definitely a science to this;
you need to know orig factory specs, then try different combos on willtheyfit.com first.
this is where the tape comes in handy.
in my case, i bought the 8.5j wheels which had huge +64ET positive offset, meaning without spacers, they would not clear the brakes.
i wanted them poking out far as poss, so also chose smaller 225/35/19 tires stretched, and had no clearance issues at all, plus given the track had been spread by 1.5" and 2" spacer either side front/rear, car handled like go kart on rails.
i recently installed camber bolts both ends, dialled in negative camber, swapped the smaller tires for wider 245/30/19 pictured below, and found the car looks much 'fatter' but rubbing on the tab under rear guard that pokes out a bit.
so i machined 4mm off the rear spacers, now technically 46mm wide.
still rubs ever so slightly on full compression, so it will go in to panel shop to grind couple mm off the tab next week.
once back i can finally set the exact camber required to tuck under, prolly around neg 1.3 deg for rear, which equates to further 10mm or so clearance at top where you need it, and use https://www.vcalc.com/wiki/KurtHeckman/camber+offset for that.
perhaps because of the spacers and neg camber, i never had any rub issues in front with 245/30/19 tires at about neg 1.1 deg, but with that you need to be careful not to dial in too much, as top of tire will rub strut on inside and steering gets a slightly strange feel in turns, as its return to center tendency is less.

rims are useless without them. i have about 30k kms on them so far, and in trying to use up last of old stretched tires, i cornered so hard fronts came off bead, but spacers held firm
Yeah, I understand...with the 64mm offset. I wonder what cars those wheels are intended for. With a 5x112 bolt pattern, I can't think of any cars that use 8.5" wheels in the 60mm+ offset range. Are they a different bolt pattern and your spacers are bolt pattern adapters as well?
they are genuine brabus 19x8.5j rims, so despite the offset i bought them, for 240nzd given they were rough, then spent 800nzd getting them cnc refinished to perfect again. i think they were intended for ml class. i think they suit c55 well; bottom pic shows the 225/35 stretched tires and 2" wide spacers on rear before i tried slightly wider
