Any 10mm Spacer Brands that Fit Properly?

You won't have any luck there. The flanges of the wheel carriers are 13mm.
Under 13mm you won't find any wheel spacers that fit, without turning off the flanges.
With 15mm the wheel spacer are also stable.
Like the look. No clearence issues. More than 15mm is to much (Testet on GTR, stock rims)
H & R wheel Spacers are very thin and not recommended. (Had this first, send it back)
Now have black SCC 15mm. (PN: 12169W) They fits perfekt.
Kind regards

Can understand your paint problem with stone chips. But you also have that, certainly a little less, without wheel spacers.
Only protective film can help here.
In my experience, you only have the following options:
0 mm. no wheel spacers. :-) :-) :-)
5 - 6 mm wheel spacer without centering.Basically bad, but work with the GT because the existing long 13mm centering is sufficient to center the rim.
7 -13 mm wheel spacers. Stable centering, only with shortening the wheel flanges on a lathe.
14 - 17 mm wheel spacer. Stable centering. Bolt on.
1 - 17 mm. Custom rims with corresponding ET. (Backspace)
Additional basics for GT Wheelspacers. You don't need any special ones for the front. (Other models with fat caps, had a problem there)
And of course you need longer wheel bolts :-): M14 x 1.5 R14 head

To add to what stenzel has said above with the items in bold (and a slight disagreement if I understand his statements correctly), using a spacer that only partially exposes the hub flange is that factory wheels have a substantial chamfer on the mating hub surface, so only relying on part of the 13mm hub flange means that it is not enough length to mate with the wheel hub at all.
Finally and VERY important, and I concur with the statement in red, especially with wheel lug bolt torques at 130 lbs, the factory length lug bolts are NOT long enough with 15mm+ spacers. The basic engineering standard is that a bolt's mating threaded length should at least equal (or better) the diameter of the bolt.
For me, there is no choice on a wheel spacer without access to the center hub flange, or a replacement machined into the spacer and, for me, it takes a minimum 15mm spacer to get enough past the factory flange to replace it providing the spacer has a replacement flange machined in.
Thank you for your answer. It is always a pleasure to read your professional comments.
Real question: Your Name: Acta_Non_Verba . Is this short for "Doing, not only talk" ?
You are absolutely right about your concerns. Never use wheel spacers without centering.
With the GT, however, it works with the 5 mm wheel spacers.
The chamfer on the wheels has an approximate depth of 5mm. (Now from my memory, without guarantee)
I checked this. There is enough left for centering due to the free high centering collar of 13mm. Often only about 7mm are left on other vehicles, then no chance.
(Supplement: the complete flange is 20mm. 7mm are used for the brake disc pot)
After mounting the rims and tightening the wheel bolts, the centering is no longer required.
The surface pressure works here. (The braking forces are also transmitted in this way, for example. Not via the wheel bolts. And certainly not via the small M6 assembly aids :-) :-))
However, precise centering is essential for rim assembly. This is a fakt.
Right, the basic engineering standard is that a bolt's mating threaded length should at least equal (or better) the diameter of the bolt. (Supplement: for steel)
However, this engineering standard is usually not implemented for rims.
There is a "regulation" (also in the WIS) that the minimum screw-in depth for wheel bolts M12 x 1.5 is 6.5 turns. (6.5 x 1.5mm = 9.75mm)
Older MB with M12 x 1.5 the wheel flanges are only 9.5mm thick. (have measured this)
With the wheel thread M14 x 1.5 (like al GT) the "regulation" means 7.5 turns. (7.5 x 1.5mm = 11.25mm)
Did not measure the flange thickness because I use stud bolts with a thread length of 15mm.
But I guess that the flange with threads is not more than 11mm.
