No washersAnd we removed the washers off the studs before we put the 20s on?

I have always thought that a bent axle will produce a rear vibration, wobble or poor tracking (i.e., crab walk)... Not really a dash shaking, which is indicative of a front end issue... even a bad DS will produce vibration up through the transmission tunnel and into the cockpit, but he's only experiencing shake in the dash area?
Let's take the rear end issue out of the equitation... Put the rear up on jack stands and BLOCK/CHOCK the front tires so car does not roll away! Put the car in gear...Then watch from each side rear-to-forward along the body lines if the tire/rim assembly has any pronounced wobble. Being it's a manual gear box this might be a 2-person job, but you should be able to stick it in 1 or 2 and let it slow roll... You do NOT want to go up to 70MPH, only slow turning the rear tires to see if axle, wheel or housing is warped.
This....I had a 1 peice I had to clock 180° to get rid of a vibration.Would disconnecting the one piece shaft and rotate it half a turn, reconnect it and see if it gets worse or better help?

Your 2012 doesn't have band tpms sensors. What does the diff upper bushing look like? Has the pinion angle been checked? Bushings on lca's, what do they look like? Lots of stuff to check to make an accurate diagnosis.
Unfortunately I don't have the original rims and tires, but the shimmy started when those were installed, and it did not go away or change at all when the rims were changed (or multiple sets of tires). Again, issue was unchanged after new power stop extreme brake kit was installed. Since it didn't make any change whatsoever with those changes, I'm about 99% sure we did eliminate those as a culprit..What you're describing sounds like effects due to out of balance rotational masses. That makes the primary culprits wheels/tires; rotors; driveshaft; rear end. Understand you checked this but Might be beneficial to switch back to original tires after spinning them first. If still present rotate back to front. That will eliminate wheels/tires. Then I'd go after rotors. In my own case I found the washer used to keep the rotors on can create a severe shaking in the front. By chance can you check run out on the front wheels?
Agree, it'd be worthwhile to get it up on a lift and run it up to speed to check/ eliminate the driveshaft/rear end.

trying to find a shop that wants to run my car up to 70 on a lift... know anyone in Raleigh? I haven't found a reliable one yet

Yes, new everything, and had the calipers rebuilt.You say you added an extreme brake kit. Did that kit include rotors?
No washers or clipsSo stupid question time. Do you have the stock rotor retaining clips installed? They go on the wheel studs. If your new wheels do not have provisions for them it will cause a vibration.
not my pic but this is what im referring to.
