So I have a 2008 g35 sedan stock and I am going to get rohana rc7's 20x9 front and rear 20x10 with a offset of 22 front and 25 rear is this too low? The only options they have for these rims are 22,32,42 offset for front and 25,45 offset for rear. What do you guys think?
My tire sizes are gonna be 245/35/r20 fronts and rear 265/35/r20. Any suggestions?

 

Forgot to mention that I am trying to achieve a deep concave look in the front and rear.
