I'm putting studded 17mm rear wheel spacers on my 2003 S.
I've picked up aftermarket aluminum lug nuts from Pelican Part.I know that Porsche make magnisium lug nuts that will also work but they are more than twice the cost.

Has anyone experienced these aluminum lug nuts?
I'm concerned with galling and most importantly stripping and having a wheel come loose from aggressive cornering.

Thanks,

Jake
