I think this disc kit is for the LBP offset on the axles. Ask @dodgedifferent2 since it's his adapters I am using. I can measure or even check a set of my LBP rallyes when I get home from the Nationals.
That would be great if you could check the LBP Rallyes as long as they are 14". @dodgedifferent2 confirmed that these will work with SBP, just the rotors will have to be drilled to SBP. I don't see an issue with this. My front brakes are the same way and many of the aftermarket disc brake companies do this already.
