Hey guys, to preface this question I know nothing about wheel fitment and specs.
So my question is would 18x10.5 +5 and 18x11.5 +5 wheels fit on a 2008 G35 Sedan? It is completely stock at the moment but I will do whatever it takes to keep these wheels, I love them. They're Weds Kranze Vishunu. Any help would be appreciated, thank you.

 

Those specs are wayyyyy to aggressive for a stock body sedan.

If you honestly want to keep those wheels, you're talking about running significant negative camber, stretched tires, and depending on the camber, may even need a to pull the fenders for clerance.

Those are honestly widebody specs. I would sell those and find another set of the same wheels but with better specs for your sedan and style.
