my friend has a 06 g35 sedan and he has 350z s-techs on his car and he just got some 19x9.5 wheels for the back and 19x8.5 wheels for the front all +35 off-sets ... he is trying to go for a flush look and i no the +35 would be perfect for the rear .. now for the front would he need spacers ?? and does the rear need to be rolled ???

and what is the best tire sizes to run with these wheel sizes

thanks everyone for the help
