wheel spacers

I am looking into installing FOX 2.5 coilovers and TC UCA's up front with all pro leaves and FOX 2.0's in the rear. Along with those the truck should be receiving 16x8 xd enduros w/ 4.5" of back spacing wrapped in some 285/75r16 tires (haven't decided on which tires yet). Just wondering if there would be any benefit to adding a small wheel spacer behind these, and if so what size spacer and what would the benefits be...any help would be greatly appreciated, thanks.

 

with the wheels sticking out 1" as is, you wont need wheel spacers on top of that... if you do, you will end up with a lot of rub on the body on turns...

 

x2 everything he said sums it up

 

thanks for the info...only time i want my wheels out that far is after i can afford my long travel kit
