I asked Loco about his tire selection and was glad I did, he is right, the tires fill the wheelwells really nicely.
Mine is a 2.5 inch spindle with a 2 inch drop spring in front and an axle flip in the back. Aside from spring removal - which can be dangerous without experience and the correct tools - this sort of drop is pretty easy to do. I did not do a C notch but occasionally wish I had.
Before, Hits of the 80's
With axle flip
And when done
And with new rim and tire combo
