thanks, u know i was just lookin into that after i saw ur post, and according to this
5Zigen website
tehy are :
New Size 17x8.0 & 17x9.0. Aluminum casting light weight wheel. 14 lbs only on 15". Its light weight feather and high quality finish in Hyper Black, Bronze, Machined and Silver make this wheel the best seller in the market
i know that the volks gram light are forged actaully, they should be all their rims are and especially the super light ones like volks, but i'll have to do some more research.
