Don't know the offset. Will they clear big brakes on 2014 AWD Q60s (a/k/a G37s coupe)

 

Yes. Those are oem sport wheels made for the sport model which comes with sport brakes aka akebono

 

Were there two sport wheels the same size for the coupe, because this is what I have.

 

You have a newer version. Idk the year maybe 14 those debuted.

 

According to this thread it was 2011: https://www.myg37.com/forums/g37-cou...hange-log.html

2011 models received new front fascia, Sport Package option for AWD, standard navigation with Sport 6MT, revised 18-inch and 19-inch aluminum-alloy wheel designs

When I was looking to buy my G the 2012 sport model came with the newer 15-spoke wheels. I have the non-sport AWD which looks like OP's 10-spoke wheels but in 18".

Assuming the prior years where those 19" 10-spoke wheels came on the sport model also had to bigger brakes then I'd guess they would fit just fine. If not get some wheel spacers to make up the difference.

 

Picked up a set and there iare no fitment issues
