1.5 inch spacers for 20 inch wheels to give the proper offset for Superlift 6 inch lift

I have a 2023 Tundra TRD Off-Road with the factory 20 inch wheels. Factory offset is +55. I have a 6 inch Superlift kit sitting on the back porch just waiting to be installed, but the kit requires an offset of +18 to +20, which I have learned is necessary due to a bracket that is part of the lift kit actually hitting the wheel.

A 1.5 inch wheel spacers SHOULD give me nearly the exact numbers I need to be able to use those factory 20 inch TRD wheels, which I absolutely LOVE, by the way.

Has anyone else installed the 6 inch Superlift kit #1026 on their Tundra and ran this setup successfully? I'm not sure if it is pertinent information, but I also plan on running Nitto Ridge Grapplers that are 37x12.50 inches on the factory wheels. Nitto says that 20x8 wheels is acceptable for that tire. I am also aware that a little trimming is necessary for a 37 inch tire, even with a 6 inch lift. I am not against an even wider spacer, say 2.0 inches, but that would place me firmly out of the recommended offset range of +18 to +20. I don't know if it is OK to go even further with the offset or not. 2 inch spacers would give me an offset of around +4.

If anyone sees a flaw in my planned setup, especially the wheel spacers, please feel free to chime in. Thanks in advance!
