5/7 Drop with 245/45r20’s

[Carp0331]

I’ve got a 95 that I’m building. Currently has cut stock springs for a 2” drop with flip kit and .5” lift shackle (also have 1-2” Drop shackles). I just picked up some DJM Upper and 3” Drop Lower control arms. I’m going to run 20x8 4.5 backspace on the front and 22x11 with 6.71 backspace on the rear. Tires I have are 245/45r20 for the front and 315/30r22 for the rear. Should I purchase either the belltech 1” coil spacers or 1” drop springs and replace the cut stock ones? Or will these tires/wheels work on the front with rolled fenders. This is a stepside and I will be trimming the rear fenders flush. Has a belltech c-notch with shorter bump stop and I’ll modify the bed for the pumpkin not to hit.
