Yeah I had a hard time searching too, but that's because of those studs I'm using. Really wanted the Kics too, but I couldn't make that work unfortunately. They should work fine for you.
I ran spacers with my previous wheels, that's why I have the extended studs. But now with the SSR I don't really need spacers anymore, already is flush (if it wasn't for me running a bit more front camber). Just a bit of a hassle now with the studs sticking out so far.
Here's a photo of the studs and the nuts I use now (Gorilla The System duplex acorn).
This won't be an issue for you with the OEM studs.
And I guess why not show a photo with these nuts actually installed.
Only still want to change the center caps to some other ones to get rid of the mismatched silver.
Can't get these sprayed unfortunately as the letters below SSR are too small.
