Any progress on this test? Trying to decide which to get....yes the only "functional" difference is the 4" of BS versus the 3.5" that the SLABS have. We are in the process now of using these wheels in a couple of DTD suspension builds so we will be able to determine if there is any rubbing on the coil-overs. We are currently running them on a Bolt-On Coil-Over setup with no issues though.
