I read a few posts about people wanting these in 20s. I saw them on ebay so they are available now. The finishes available are chrome, competition grey, satin black and machined face with light silver windows.
I don't have prices as I am not selling them, but the 20s are already on ebay. The 22x9's weigh 34.5 lbs. For reference, the stock oem forged 20 inch srt8 wheels weigh 30 lbs. I don't have weights on the 20s yet.
^^Probably not too big a difference. Your stock wheels are cast. They undergo extensive testing before producing these. The pics of the 22s are the testers being tested to make sure they meet specifications.
