thanks!!! I think its 1.25" drop... And yes, they are available staggered. They come in various offsets in 8.5", 10, and 10.5.
If youre set on going staggered, I would probably go with 10front and 10.5 rear, so you still get some good concavity up front. The 8.5's have flat faces, and IMO not as aggressive looking.
