20*8.5 +33 OFFSET
20*10.5 +30 OFFSET

How would these specs fit on our sedans? I also have coilovers and rear camber kit ready to be installed as well. Would I have to roll fenders?

 

Not a stance expert by any means, but fronts are fine, rears will need a roll. You probably won't be totally flush with those.

Probably shouldn't have started a new thread for this, ask in here (https://g35driver.com/forums/g35-sed...on-thread.html) or any of the hundreds of wheel threads.

 

You will need to run some stretch,camber and rear fender rolled flat. The fronts are fine, but the back will require some work..
I ran 20x10 +25 (1mm less agressive than your specs) with 255/30/20, fenders rolled flat, pulled a few mm, and 2.1 degree of neg camber. The wheels sat pretty flush, but it did take a little work.
