Although the 2016 IS 300 F sport comes stock with a staggered setup, has anyone done a square tire setup for cost effective? Just curious as to what size you are running and if you ran into any issues. I can’t find any wheels that I like for the IS which is why I am thinking about going down this route..

 

You can do any square setup you want really...17's, 18's, 19's, 20's.
Your width would be limited to 9 inches...since that's the easiest to fit on the front and rear.
Offset would be around +32 to +35 depending on width of the rim.
You could go with a larger offset, but may need spacers at that point...like if you did a +45 offset, then added a 10mm or 15mm spacer.
