16x9, 4 inch backspace, no spacers, just a little bit more poke out of the limited fenders than santacruzrunners pics. i personally like the way they keep the sidewall of the tire straighter myself over a 16x8, depends what you are going for though.
I'm looking to put some Pro Comp Steelies on a stock 2001 SR5 and they only have 16x8. I need to replace the stock 16x7s and i'm looking to do tires at 265/75 R16.
16x9 seems pretty wide IMO, possibly too much. In the past I have run aftermarket 16x8 and I am currently running 16x7 Toyota wheels on 33s with no issues.
