I have a 2015 Gs350 Fsport AWD. recently purchased and received my Airlift 3H kit and found the wheels I want to pair it with. Originally considered going staggered (20x9 front, 20x10.5 rear) as there are plenty of examples to go by on many websites like fitmentindustries.com , but being my car is an AWD, its a mathematical nightmare trying to figure out exactly what configuration to get to avoid shredding my differential. I've also considered doing a box setup to make it easier but am afraid I cant achieve the look I am going for. Can this model fit 20x10s all around, flush setup for drive height and full tuck when completely aired out. I want to avoid or at least minimize any fender modifications or excessive negative camber as tires aren't cheap. I'm ok with a slight stretch on the tires if needed. The rims I want are offered in any custom offset from 0 up to +45. I cant seem to find much, if any information on AWD model wheel setups and need help. Please advise!! thanks guys

 

If you want a square set-up I would go: 20x9 +33 and 20x9 +28. That should allow full air out but it wont be perfectly flush.

 

You can easily do square set up if you don't want to mess with fenders. You can even buy spacers for the rear if you want to poke it out a bit.
