Yes it would accomplish the same thing, but in my experience moving out the rears scrubs off speed.
I think if you put a good amount of bend in the DFW and with the rears canted you don't even need to cut back the DFW body side. The positive cant on the DFW and the negative cant on the rears naturally makes the rear wheel behind the DFW stay off the rail. You rears will not be centered on the rail, but I think they will be off the rail.
This is true right? Anybody else agree?
