@arathol, following your suggestion, I researched McGard, and the black ones I found (# 84538) are 1.45" in length, compared to Mazda's standard 1" ones. I am using Mazda's 18" dark alloy wheels.
Please, did you find another McGard option that has shorter than 1.45" lug nuts, or are your's that length? If the latter, might you have a picture of them on your 17" wheels please?
