Are you planning on using your new wheels for daily driving? If so I'd recommend something a little less expensive. Forged aluminum rims are great for saving weight but beware of any potholes or other road hazards. You can easily bend or warp one of those expensive wheels with day to day driving. There a plenty of other brands that sell wheels that weigh a pound per inch diameter. An extra pound on each wheel is not going to make any difference to you on the street. I do understand that you'd enjoy sporting some nice Volks, hell I would too. But for the price to curb rash ratio I'd rather not. But that's just me.
However....if you are planning on racing, unsprung weight makes a LOT of difference for those extra 100ths of a second.
