So im trying to decided on what size rims to purchase, looking at a 20" rim but I need advice on the offset/dimension. I want a flush look I hate when the rims stick out past the wheel well. Also droping on progress springs and I dont want any rubbing issues. I like the deep dish style rims also.

Thanks Guys

 

The offset on the OEM wheels are +40 so if you stay close to that you should be fine
This should help with the tires
