Looking at grabbing a set of Forgestar F14's but I want to do something most people haven't done or wouldn't do by running super deep concaves in all four corners.
Specs will be:

Front: 20x10.5 et35? and either 285/30/20 or 265/35/20
Rear: 20x12 et30? and either 325/25/20 or (305/315)/(30/25)/20

Will be dropping about 1" to 1.5" on Powertrix Sport/Street Coils. Obviously things are still a little up in the air, tire sizes depending on what will clear and being able to find them in those sizes. Will be doing a fender roll and possibly a pull depending on what's needed to maintain minimal camber.

But can anyone with a little more experience point me in the right direction for offsets? Should I go with more aggressive offsets or will that be just enough to go flush without spacers and clear the suspension? I feel like I'm on the right track but still a little lost.
