If the tires/wheels are fine, you might try having an alignment shop look at everything while doing a realignment. Usually a front-end shimmy is not actually an alignment problem, but they might notice that some bushing or ball-joint somewhere is worn out and causing it, or some nut on some adjuster has come loose, etc. But maybe have a second shop rebalance the wheels first? It's usually like $40 tops to rebalance them all. Look for one with a Road Force machine (which normally isn't necessary, but might catch more-subtle issues).

I did not have this problem prior to the slip on spacer install. I had 15mm bolt on spacers and there was no shimmy.
Old tires had the shimmy and I replaced them Tuesday with brand new tires (all around) and the shimmy still exists. It basically HAS to be something to do with the newer slip on spacers or the new longer studs. I just dont know how to identify which is wrong other than buying another set, perhaps H&R this time instead of the cheaper ichibas that I'm running now. Rear spacers are bolt on Z1s that were on the front.
I appreciate the detail and double checking you are suggesting! I will pull them off again this weekend and sand everything down, though I did wipe them down prior to installing. I havent had the car up to speed (anything over 40) in the past day since having the front up in the air and trying for the 4th time.
I'll try again and keep you posted. I dont have any means of checking thickness so maybe I'll go pick up my caliper set from my mothers garage (yes, I'm 31, a home owner, married, etc and I have yet to pick up ALL of my tools from her garage
).
Thanks!!
