or 20mm to make my rims flush to fenders and bought a 20mm bolt on spacer kit but wanted to see what others are running because the spacer looks awfully thick. Guess there's no way to tell until I get the spacers on. My ride height is .7" more than yours so I imagine camber will need adjusted a little. Just a little lazy since it's only 20 degrees here and the Z is put down for the winter.
