Spacers are primarily for looks if your going in that route, as I have used 10mm on my +43 making them 33. They looked great, but damn rolling like that while sitting lower gave me issues, handling was worsened in my opinion,turning radius sucked, and I hated rubbing on the fender(had to roll it more). But Im not going to lie, the flush look is great. 25mm spacers are what your going to need OP if you want to look flush with the stock wheel and tire set up. Madvillian I believe has that set up, or HAD that set up.
