I've been using the KD Dub Yahs on my FX35 for 3 yrs, now, and will be buying them again. They're a great tire.
They're still holding up well for having about 100 autocross runs on them and at least 300 track miles.
Probably about 20K on them, now.
I'm hoping to get one more summer out of them which will mean at least one track session and 20-30 autocross runs

VLSD prevents one rear tire from spinning significantly more than the other. This has various effects on handling through corners and also straight line launches.
A car without any type of limited slip differential will burn up one rear tire. This makes the car hard to control in a corner and also prevents you from putting full power to the ground in a straight line. That said, given what you've described was your situation, VLSD would not have saved you.
I won't write an essay on limited slip differentials here, as there are plenty of good resources on the internet. Google it.

Actually I think the G does under steer more that other sport coupes I have driven unless you compensate with some juice. Its strange the back would kick out without you stomping on the accelerator.

tried to control the car swerving back and forth finally jumping over the center divider

The car behaves differently on throttle vs off throttle. Even just "maintainence throttle" will promote neutral handling. Off-throttle or deceleration-inducing throttle applications will make the car understeer when pushed.
This is mostly down to weight transfer but also has to do with traction budget at the rear.

Weight distribution is important, but understand that understeer can be dialed in by your staggered tire setup, spring rates and dampening, and sway bar stiffness, degrees of camber, etc...too many ways to dial in understeer beyond a 53/47 weight distribution.
I think you can do your self a favor by taking a 1-day performance course. I drive a 430 hp, 390 ft/lb G35 Coupe with most of the understeer dialed out every day with VDC off. Then again, I have 5 years of seat time. The car has great balance and limits, but any car will spank you if you don't respect it.

I went into the turn to see wat the car can do. No, I did not give it gas while going 45. I just wanted to see how good of grip the g37 has. Wasn't trying to drift nor mess around.
