Critique my Suspension plan

Good call on tire size. I had changed them to the taller 50, but forgot to find the right size for the front. So what would be the best size for the front ? I am OK with a bigger bar setup. I don't mind something like the Hotchkiss front and rear bars. Just didn't know if it was necessary. And can you tell me more about how the rear leafs and where to get them.
