I can get any of the adapters or beadlock rims. The other nice thing about the Dace adapters is the fact that they fit over the 14mm hex, so they work on anything with this hex size. The prolines replace the hex(so, they won't work on certain vehicles, like the HB LSP, as the actual axle is a different size).
All beadlock rims add weight. Also, with a lot of power, they can let go of the tires sometimes as well(in other words, I wouldn't use them myself-I have a set of black maximizer beadlocks with the standard and wide offset adapters sitting around unused for 2 years!). To each his own, though. If you want them, I can get them. I don't know if the newer proline beadlocks hold the tires any better, but I am sure they add weight.
