I've always thought the argument against wheel spacers was based on the imagination of someone who didn't understand how hubcentric spacers work and heard an urban legend about some low rider popping off wheels on Ventura Blvd cruise night in front of a laughing crowd.
Modern CNC production is precision defined, I have no hesitation adding hubcentric spacers that meet spec.
You're right to say
most people don't understand how spacers work - hubcentric only means applying the force on the hub evenly spaced; it doesn't make it safer to run as you will still have added pull-out force on the studs and hub regardless; math is math.
I was bored and did the math on our trucks using our baseline rebel weight, payload max, axle max weights and came up with a 1" spacer = approximately 8 ft/lb of pulling force added to your studs and about 17 ft/lb if going with a 2" spacer with oem offsets. will that cause a failure? No. does it put you closer to failure of stud shear / pullout? yes; slightly but still yes.
OP, sorry to super-derail; lets see some pics of your install already! figured by now you'd have bought the parts haha
