chillymostly,

I got some Genki brake discs last year, and they are on my VDF - Haven't had a problem with them, my wheels are still on tight. They are made of aluminum, and as joeyhatch11 says, they're for show and not much else.
As bling they look great, but don't do much beyond that. If you're still wanting discs, the Genki ones fit better than what youcurrently or are wanting, to use.
