Im looking for rims

In my search for rims for my Chevy, i came across some on a show truck and have been unable to find them.  Recently I saw them on a Chevy Silverado on the show Cribs.  They were on Ricky Carmichael's truck.  They are a five spoke design.  The other place the i have seen them was on a Black F-150 that had Ground Force lowering kit.  I emailed both GroundForce and the magazine where i saw the truck and have yet to get a reply.  If anyone out there knows of the rims that i am talking about please tell me.
