Another vib thread, should I get smaller shims??

Sorry for another vibe thread. When I first had the truck with revtek 3" with wheelers steel wheels and 265 bfg at I don't recall having any vibes in the floorboard. Then toyota did the rear leaf tsb and the floorboard tsb. Went back to stock. Then had 5100s at 2.5 and had vibes, dropped the front to .85 and had very minimal vibes. Now running icons at 2" with toytec tsb aal and 3 degree shims/ carrier bearing drop and still with vibs at 35-45 mph. Should I get smaller shims?.......love the look but can't stand the vibes.
