Those knock-offs weight a ton. I shopped all of em, and the knockoffs were from 5-8 lbs more than the FR pieces and weren't that much cheaper than the wholesalers. The rotating mass makes a HUGE difference.AmericanMuscle.com has them for around $190 a piece I think for Chrome 18x9. They also have replica ones for once again I think $170 a piece. I would check Ebay and see what you can find there.
