My wheel nuts (the collared / washered variety) are factory spec for pre-facelift GRX mags - not GQ. So, the only thing I can assume is that there was a change with Mags from pre-facelift and post-facelift. I know they look pretty different.

Seems to me like there's no possibility that I now have the wrong nuts. And my car is a GRX with mags. Nou toe nou. There's one for you.
And mine is also GRX - albeit older. There's one for you.
In all honesty, whilst I don't have a post-face-lift GRX, and can probably not really comment in that regard (as we've seen), I've seen some serious crap when people run mags with nuts designed for other wheels - most recently, some guy I know with newer Hilux rims on an older Hilux attached with "steel rim" nuts. He lost a wheel. Nobody was hurt, but it wasn't pretty.
In short: I was just making an honest "word of warning". Anyways, getting back to work.
