HRE / iForged
Call them knock offs if you want... They really aren't. The styles are all very similar, but that is the same with many wheel companies. They are still completely custom 3 piece wheels, made specifically for your car. They are cheaper, but the quality is right up there. Lay an HRE wheel and an iForged wheel next to each other, see if you can see where the iForged piece is inferior. I can gaurantee you won't be able to.
The price is up there, but at least that keeps everyone from having the same exact wheel. If you want to go with something cheaper, but similar, you can go with Intro.
Get a 2 piece wheel, with more expensive looking styling, at a cheaper price.
