Hi guys who are running light weight Enkei rims.

I've been running RPF1's for about 2 years now. Bought correct shape (cone?) lug nuts (made of steel I think), which is evidence by contact marks along the entire mating surface. But after removing and attaching them many times I'm starting to see fine flecks and splinters of alloy coming off with the lug nuts. And of course the black paint came off ages ago. Is this something anyone else has had?
I figured to prevent damage I would invest in some Enkei brand aluminium lug nuts which are made of 'super hard aluminium'.
Really don't wanna torque them down less than the (Honda) recommended 108nm as I have experience losing a couple that weren't tight enough before
