Yes, I have a minitub moved into the frame rails and run MT 275/50 ET Drag Radials.
Frame is not notched, just moved the wheel well.Just to be clear, he said, " just move the tub over to the frame".
You said, "minitub moved into the frame rails".
Did you cut into your frame rails & move the tubs over into the frame?
There is a big difference in these two examples.
