I recently been driving my G kinda hard in the cornering and turns. I noticed and felt alot of tire lag in traction on the front. It feels as though the tires are gonna fall of the rims, like they are under inflated, but there not. I hear a rubbing sound from them when i dive into the turn. What do I need to solve this? Sway bars? I have the 17" factory rims and tires. I need better cornering..

That is probably the front tires losing grip, causing the car to understeer. There are quite a few solutions to better handling: adjust tire pressures, get stickier tires, get a bigger rear sway bar, get aftermarket suspension, etc.

 

Infiniti recommends 30psi for the tires, but that's for daily docile street driving. I autocross my G35, and on those days, I air the tires up to 40psi front, 38psi rear. The higher pressure keeps the sidewall from rolling under in the hard corners. Of course, 40psi is a bit rough riding for daily commuting. Running 35psi for daily driving may give you a better tradeoff. The tires can handle up to 44psi without a problem, but that's actually too much.

Try the tire pressure first. Then look into sway bars and better tires. I'm staying away from sway bars at the moment only because they'd kick me out of stock class in autocross. However, the G35 does roll in the corners quite a bit even with the sport suspension.
