How long til I ditch the inner fenders?

Well, it's been 7000 miles and the 15's are finally shot on Fast Orange. The truck has a 3.5"/5.5" drop with 255/70/15's on factory 80's truck rallye's, 29" total height. The tires rub on the outside edge of the inner fenders right now, so for sure I need more backspacing.

Here's the dilemma: I want to go lower, 2" on each end. That puts me at a 5.5" front (3" spring, 2 1/2" spindle) and 7.5" rear (5.5" leaf flip, 2" shackle). I will also be purchasing 20's. Coys C5's to be exact, 20x 8.5" all around with 5.25" backspace and 255/35/20 (27" tall tire).

I have stock inner fenders on the front, and will be keeping them. Will this all work out, or should I consider not going as low? I notice Coys also make a 20x7, but narrow 20's are hard to come by.

if you go for more backspacing you're putting the tires further into the inner fenders causing a worse rub than you have now

The 20x8.5's with 5.25" BS will tuck 3/4" more than your ralleys.
(this should help with rubbing on the outside edge of your inner fenders)
Keep a short tire up front if you plan to keep your inner fenders.
Like a 245/40 or a 255/40.

Thanks lolife99! I really like the stance on your C10. Mine is only about 3 1/2" down in the front right now, and I'm looking at going 5 1/2" on 20's, so that's where the trouble started.
