Here's my G (Sorry for the crappy pics)

 

Welcome to the club! Nice looking coupe! Enjoy the road with her!

 

Thanks (: now I don't know what to do next with her lol any suggestions?

 

Hey i’m trying to get the biggest tires on my 2007 g35 sedan what you think the max i can get i was looking at 295 rear and 265 front

 

You're off to a great start and have a great canvas to work with.
Based on existing mods, I would consider the following:

0. Make sure all maintenance is done first
1. Swaybar upgrades, coilovers and camber arms
2. Nismo front bumper, Impul sides, BlueBat tail overlays and matte or glossy black rear diffuser overlay
3. Fast Intentions Intimidator exhaust
4. 5/16th ISO spacer
5. zTube
6. Grounding Kit
7. Audio upgrades
8. Custom painted headlamp trims (Metallic Black/Gray Combo) since it appears you already have the 06+ headlamps

I would call it a day after that.

Some folks here go/went way further than that...YMMV
