Swapping to spherical bearings will actually add to the wear on other systems in the car because it directly transfers forces. Poly acts like a spring and can bind, so it effectively ups the spring rate of whatever system it's in. It can deflect for sure, but I would bet that going spherical (which reduces overall spring rate) will have the same, if not more tire wear. Wheel bearings go out on those cars on r-comps. Swap to the 5x114 knuckles to solve this. It's not the poly that's hurting those.

I have run sphericals in the rear suspension for years without wallowing out any holes. I recently sphericaled the OEM arms up front but expect the same results of "I need a tad more spring rate".

Like Ham said, there's a lot of common issues in SM, and until you spend some time massaging the inner and outer fenders you'll rub, and even then you'll want more grip so you'll go to a bigger tire, which will rub again, so you'll modify again

Thanks for the help guys! To be clear, my tires have about 1/2" clearance from the inside edge of the tire to the unibody at the height of the center of the axle, but it is flexing the lateral link bushings enough that I'm rubbing pretty aggressively there. Also, due to budget concerns I'm running a 255/40/17 BFG Rival (yes, 200TW) and having these issues. Can't imagine how it would be with some purple crack of modest size.

5x114.3 knuckle conversion is in the plans, but it will be a big expenditure so for now I'm getting good at pressing wheelbearings. haha.

I run a 335 on a 18x12 +20 wheel with a 5mm spacer our back and don’t rub on the inner unibody. That’s what’s possible in SM.
