RE: 18" bullits
I’m putting 315's on mine this weekend along with 2" drop I'll post pics and let everyone know of any rubbing issues. And I didn’t adjust my speedo, because due to the lower profile tire and lager rim the speedo is only of a small amount there is a tire/speed calc, link.

18x10.5 rears and 18x8 fronts. 315 will fit no problem. Mine has 2" lowering springs and I have plenty of room to fit 315's under there. (which is what I am going with when these are burnt off)
