I just got these 19 inch coupe wheels running staggered setup on my g37 AWD. 245/40/19 front 285/35/19 rear. Is there anything I need to worry about suspension wise? I’ve had bad history with wheels damaging my suspension 😭

 

You should be good to go with that setup. Your 285/35 are about as wide as I would go on the 9 inch wide rear rims. You could throw on some 10 or 15 mm spacers on the front just to bring the fronts out a little and more flush with the fenders, but that is just my opinion.

 

You should be good. The only thing that really matters is rolling diameter, and your back and fronts are within 1% of one another so you're fine.
