In search of magnesium mini lites

Before you spend big bucks on these...unless you have some serious mods going on, those 15x8s won't do you any good on the front.

Also, aren't magnesium wheels known for being fragile/brittle? Yeah, they're extremely light weight and the originals look cool as hell..but for all that extra cash and the possibility of a cracked wheel and/or a white hot wheel fire...Aluminum might not be a bad option.
