Truck looks awesome.

My leaf spring truck with a flip came down 7". I removed the factory bump stops as well as the steel pad that is on a leaf axle. (Never owned a coil truck other than a c20 Sub so not sure what they look like.) I put the DJM urethane bumps on the frame above the axle. They hit occasionally but not often enough to c-notch it.

On your fronts, I'd look at a wheel with a different width/offset in addition to a narrower tire maybe? I have 27" tall tire on the front of mine (235 55 17) and with about 500 miles under my belt I have zero tire rubbing anywhere front or rear. And rears are 29" tall (275 55 17).

Taller tires are one of the things IMO that really help the look and stance of these trucks lowered.
