Driver side is lower than the passenger side by about 3/4 - 1in. any thoughts on why this might be?

 

You have fully stock suspension?

 

Your driveway has settled and is no longer level?

 

Did you just get the G? If so, the previous owner may have been extremely heavy and overburdened the suspension on one side, I've seen this occur on a few vehicles.
Just a thought.

 

Lol I thought about this too but I think it would take a sumo wrestler daily the car to make the spring lose its shape like that.

 

Yep, it's doubtful, would be best if OP put the vehicle on level ground and measure from the ground to the fender on each side and see exactly what the difference is at all four corners.

 

I am the 2nd owner. purchased at 32k miles. its a 2012 g37 ipl 6mt everything is stock. i have visually checked the level of the car on several different surfaces and the driver side is still a bit lower. I have yet to measure it to see the exact differences on each side. With that said the car drives straight and it seems like the suspension takes the road somewhat well with it being a sports car and all.
