Looking For Wheel Recommendations (12' Gt)

Looking for recommendations for wheels and tires for my 2012 GT. I love the way it currently sits (see picture), drives, and handles. I'm running P245/45R R19 in front and P275/40 R19 in rear. This was the setup when I bought the car several years ago and I have stuck with it.

I'm looking for a gloss black, staggered setup, with 9" wide in front and 10" in back. I can spend about $300 a rim. I know all my wants limit what I can do.

I'm currently looking at Flow One F3's on TireRack but do not know anything about the brand. Also looking at sticking Firehawk Indy 500 tires on them.

I'm in the Metro Detroit area if anyone knows a guy.

Suggestions are encouraged!

Thanks for taking the time to reply! I just can't wrap my head around tire size and what that is going to do to the stance. I see the tires that come on those wheels are 285/35/19 and 305/35/19, what is that going to do to my stance and ride?
