I saw these pop up just before new years. I think this is kind of a big deal for ATX. It gets them into the game for say the TJ market. The 17x9 with 3.5BS (Slab) had the wheel stick out too much. But now with 4", it is in the mix with the other beadlock makers.
There are a fair number of us TJ/LJ/YJ etc types running 37" rubber but the only wheels with appropriate back space is beadlocks when moving to 17" rubber. Not many companies make 37x12.50R15 tires. Coming from an area where fender and mud flap laws are enforced this works.
My next set of tires will be 37x12.50R17 and these wheels look like the best ones to get for my application. 2014 Christmas shopping if there is any money left after finishing the kitchen and buying a commuter car.
