From what I've read elsewhere, they aren't actually shipping yet. They are manufactured overseas. At this point they are exclusive to Year One.
Initial feedback on the 17" Magnum quality has been very positive, so hopefully that is a good indication of we can expect on the Rallyes. I definitely think the styling on these scaled up better than the Magnums did.
Compared to the prices of the other larger than stock Rallye replicas on the market, these are very reasonable. Credit the one piece cast construction (and overseas manufacturing). In fact, they are priced competitive to the 15" reproductions.
Year One has offered pricing of $699 set on the Magnums. It would be nice to see that price on the Rallyes.
Haven't seen a weight number on these. Magnums run 26 lbs and 28 lbs on the 17x8 and 17x9, respectively. Not light, but fully dressed with tires that will be around 55 lbs, very close to that of steel 15" Rallyes. A 15x8 Rallye with a 275-60-15, cap, and trim ring is about 58 lbs.
