How can I correct "loose steering"?

Well I checked the play by turning the steering wheel from outside the car. It seems like the tire moves like it should when I turn the wheel, in other words there isn't much or any play when I turn the steering wheel before the tires start to move. I guess what I'm feeling then is more a lack of sensitivity...I feel like I need to turn the steering wheel too much (in my opinion, compared to my friends 07) in order to get the proper response.

Try putting a couple more PSI of air in your tires, specifically the fronts. That may take away a little sluggishness or lazy feeling from the steering. Tire compound and air pressure can make big differences in how the steering feels and reacts.

^ those two factors affect responsiveness alot. The right tires make up about 90% of a good setup. Following that I would look into toe, camber, spring rates and dampening. They all work together to dial in/out steering response.

Yep, I'm starting to think it's the shitty tires I have on there (goodyear RS-As). I did the move the steering wheel from outside the car test and saw that the tire does indeed move as soon as i turn the wheel, so there doesn't seem to be any excess play.
I'm looking at replacing my POS tires with some Bridgestone Potenza RE-11's, hopefully that will fix the issue.

Got the RE-11's put on...amazing tire as far as grip is concerned but steering response/looseness still feels the same as before.
I guess I'll check to see if the compression arm bushings are worn this weekend when I do an oil change, if not I'll probably take it to a good alignment shop to see if they can figure out the issue.

Good luck... sucks the tires weren't the answer.
I've never heard of it but maybe the steering rack or pump is going bad? May be worth looking into if you find all your bushings are ok.
I'm still a bit confused by your descriptions of the problem though. Is the steering heavier and slow to respond when moved quickly? Or is it loose, and light... excessive play and movement before anything happens?

I don't detect much if any play. In other words, when I turn the wheel, the tires do seem to react immediately. The problem is that they don't turn as much as they should be so I have to turn the wheel more to get the same effect compared to my friend's Z. It also seems easier to turn my steering wheel, which contributes to the feeling of looseness. This is really apparent when going through some 30mph-ish switchbacks...the steering feels really loose then. I hope that's a little clearer...

I'm no expert but I figure i would give my 2cents. This wouldn't have to do anything with travel of the wheels vs. the steering wheel but it would make a huge difference in your steering wheel feel and how it comes back when you let go after turning. I'm referring to the adjustment bolt that looks like a huge nut on the power steering rack. Tighten it a little to remove some slack and that might just do it.

I'm really thinking its a difference between alignment specs of the two cars you have driven, a bad bushing on one of ther two cars and can even come down to tire pressure of the two cars.
I own 2 350Z's, and i drive plenty of other Z's when i work on them. I've driven around 15 different cars this year, none of them feel the same. No 2 cars are a like, but there is crazy difference between the different Z's.

I don't know if the rack was ever replaced before this. I would imagine that it's OEM since the dealer replaced it. I just checked with my friend's car, the wheels have the same number of turns lock to lock and the tires look like they are at about the same angle between the two cars when the steering wheel is turned all the way to one side.

I'm taking it to a specialty alignment shop tomorrow morning, hopefully they can fix whatever it is that's causing the looseness.

That's not a stupid question at all...
Anyway PeterSellers good luck, I hope they find your problem. I'm running out of ideas... Although it would help if I could actually drive and experience it myself. Trying to understand descriptions in text from someone who (no offense) thinks differently and has different perspectives is difficult.
The ONLY other thing I could think of that would cause looseness (not such as I believe you described it, but i'll mention this anyway) is the steering column "collar". This is a plastic piece that connections the upper and lower column shafts. This piece had cracked on my Z after a collision with a curb and since then my steering had about 3/4 inch of play in it. Where you can move the steering wheel back and forth but it had no weight and didn't move the wheels. I don't believe this is what your describing, but thought it was worth mentioning at this point.
You can see the (white) collar by lifting up the rubber grommet at the bottom of the column from within the cabin. Although this area is definitely something for the experts or the mechanically inclined with a full Factory Service Manual as a guide.
