Wheel spacer size with RC upper control arm?

[bpigg27]

Hey I got a 2023 lariat and just put on the rough country 3in m1 shocks and the rough country upper control arms. I was wondering what would be the minimum size wheel spacer I would have to run with 35/12.5/18 Toyo mt if anyone could help. Thanks!

I had to run 1/2” spacers with extended thread lug nuts to “clear” my JBA UCAs with 35x11.50 on stock +44 17” wheels. My tires might actually still kiss the UCAs at full lock.
