COBRA ESQ

My head is spinning from information overload. I have a 2014 q60x sport (a/k/a G37x coupe). I am looking to go with a stock 19 inch rim for winter tires?
1) What is my stock offset, 43 or 45?
2) Does square refer to both overall tire diameter and width or only diameter?
3) To clear the big brakes will any stock 2014 and earlier infiniti 19 in rim clear or do I need to also pay attention to offset?
4) Will a 19 inch Q50 rim or post 2015 Q60 rim clear? Is the offset so different that they will run or look fugly.

Thanks

Here's a good site for your wheel specs, both the 18 & 19 oems are +43 offset
https://www.wheel-size.com/size/infiniti/q60/2014/

Square refers to all wheels/tires the same size

All OEM Infiniti G 19" coupe wheels will clear the BBK, not 100% sure on all 19" Q50 sedan wheels, but I'm fairly certain they will.

The only real different fit would be the 19" coupe wheels sold for the convertibles, they have a +30 offset, this is still a good fit on a coupe, just push out to the fender another 13mm from the regular coupe 19x9s.

So if I understand things correctly, different width 19 inch rims front and back mounted with tires which because of the chosen aspect ratio/diameters are the same overall diameter are not "square". But can nevertheless be used on a AWD vehicle because the overall diameters are the same, or within 1-2 %.

It is the 19' diameter, not the offset, that allows the rim to clears the brakes since the offset only effects how far wheel sticks out (if at all) from the fender lip.

And assuming the above is true, then ..... 2009-14 19" sedan rims will clear the brakes but aren't used on my coupe because the aesthetics of how far the tire will extend beyond the fender due to the different offsets?

When blnewt said any 19" couple rims would fit, I assumed that 19" sedan would not. You may be right that 19's were not available and I read too much into his comment.

Yeah, the Q50 has a wheel upgrade pkg w/ 19s, I believe I've seen pics of them on Akebono equipped Q50, not sure if it's part of the Q50S pkg or a separate upgrade??
