This was my G set up:
I recommend getting a similar suspension set up to what i had; Tein springs / Tokico shocks. And then setting up your wheels and tires properly so that you dont rub but also to minimize wheel gap (stance it).
This set up, with SPL arms and a good alignment, was better than a brand new 335i Msport off the lot. Infinitis are great cars, you just need to unmute them a bit.
There was a local guy who bought a bunch of gear off me with a G37 sedan that just did wheels like what you posted, coilovers and exhaust and the car looked and sounded incredible… you could get a similar stance with spring / shock and still DD it all year round.
