From the research that I've done 10MM on the front and 15mm on the rear seem to be the best combo. In the past, I've had the best luck with the H&R spacers and longer lug bolts. Prices on the internet vary widely, best prices seem to be in the $85 - $90 range.
Read up about spacers a little more. Seem like alignment is not an issue but pushing the rotational centers outwards might put more force on the wheel bearings than factory specs.
Now I will like to know the specs (size and the offset) for 20" and 21" AMG rims from the factory. That will give me an idea on what is the range i can push the offset before severely shortening the wheelbearings lifespan.
I have attached a picture on how much gap I have from the surface of the rim to the fender trim.
What is the minimum size spacer I can get away with to achieve a reasonable look.
I do not need it to be totally flushed.
Ran Spacers for 4 years on an X5 4.8 M Sport and have run them with the winter tires on my '13 E93 M3 for 3 years without any problems; am sure that Mercedes Bearings are equal to the quality of those used by BMW.
Were your applications used for the rears or fronts?
Read about scrub radius (definitely will add to the scrub radius if spacers are added) and how messing with them can affect the handling of the ride. I guess it is more for the front but wondering how does it affect the handling if only applied to the rear wheels?

I don't read German but can this set fit out GLC?
Concerned that the stock wheel lugs might be longer than the spacer thickness?
Ran Spacers on all 4 corners of the X5, am only using them in the rear of the M3. Effect is no different then installing the same size wheels with less offset/backspace than the originals and is quite common in model specific aftermarket wheels designed to position wheels so that they aesthetically fill out the wheel wells.
You want the DR Series Spacers with longer lug bolts, not the DRA Series Spacers pictured above.
I will need to have the factory bolt specs before I can choose the DR series. I do not have the tools and avenue to remove the bolts for measurement short of bringing the car to a wheels shop just to do that.
Thus still searching for the factory bolt specs for the 19" AMG rims (non-staggered)
GLC bolt Circle is 5 X 112mm
Wheel Center Bore is 66.6mm
Lug Bolt thread is 14mm X 1.5
Stock lag bolt length is 27mm
To determine the required lug bolt length add the thickness of the spacer that you have selected to the length of the OEM lag bolt, i.e., if you are installing a 10mm spacer, you should purchase 37mm lug bolts, for a 15mm spacer, you will need 42mm lug bolts...etc.

Is the bolt length the same for 19" vs 20" vs 21"?

can a forum member verify an H&R spacer that would meet this criteria? I believe I want to try a 15mm spacer width all around to see how that will work
Passenger Car lugs are 27mm, when I measured those on my '17 GLC W/19" Non Staggered Night Package Wheels, the OEM/Stock lug bolts measured out @ 45mm, if yours are the same, you would need 60mm lug bolts W/15mm Spacers.
Alright, I know what lug nuts I need now. If these are black spacers, I will take them and Paypal tonight. My rims are black and I believe silver will have to much contrast. Wanted to go 18mm in the back, do you feel that is to much?
