No problem dude. 1 Piece Forged is just that, a wheel forged and cut from 1 piece. A 3 piece wheel is composed of 3 pieces 1 the center disk and 2 barrels inner and outer. Most forged wheels are manufactured using 6061-t6 tempered aluminum. I will post some pics of the components used to build a 3 piece wheel on Monday when I get back to the office to give you a better idea of what they look like apart... On the website there is also a little bit about why forging is better then casting and so on.
