Subframe fit

Hello,
I am new on here and trying to find may way around. I would like to know if any one out there has installed an Alston chassisworks subframe and what kind of front clearance issues they are having if any. Also My subframe kit drops the frontend  2 1/2 inches and i'd like to run 17s on the front 18s on the back any idea on the widths? I am Mini tubbing the rear also.It should handle 12" easy the front is what I need help with. I enclosed a few pics of the car torn down. Any suggestions would be appreciated.
