A stock '02 Z will hit 174-5 in 5th. Shift to 6th and you slow down. Don't ask me how I know. 
I think with stock 3.42's, it's geared to go about 250 @ redline in 6th. To acheive that would take more than 1000 hp IMHO. Air resistance/ drag is exponential, and requires bigger HPgains to make smaller top speed increases, as overall speed is raised.

About 500, will get you to 190 mph.
750 about 220.
If you are not pro driver or have at least fifteen years racing under you belt and perfectly setup car, I would highly recommend not attempting it.
Stock, at about 145 mph, these cars tend to lift and at 190 the tail will lift.

Highways have all kinds of issues.
Many more occillations. Various debrie; oil, dirt, moisture, etc. Traffic at substantially different speeds, which could result in major changes in momentum. etc.,etc.
EG. I would have zero problem going down Sebring or on the Autobahn at 200+ mph. in the right conditions.
On the highways here, I always use judgement. 120-180 max. depending on conditions.
I did 180 a few days ago. I have a full custom C5R type suspension.

I have had my Z06 at 180+, and it was still accelerating, when I had to slow for traffic up ahead. It was completely stable at that speed and the brakes pulled it down to 75 quickly and in a straight line.

When have to change direction/momentum (turn) at speed, then you have worry about keeping max adhesion at 145.
I would not do a spoiler without addtional downforce on the nose (air dam, conards, hood). All you are going to do push down the back and create lift on the front.
Most of spoilers/ground effects sold here are junk.
1) Only use ones that have been wind tunnel tested.
2) tested at speed
3) Used at the track.

I do four wheel skids at 90-120+ mph when I am feeling perfect, very motivated and conditions are right.
Pumba, above is running conards and good 37 degree spoiler. Plus it look as though he is lowered to T-1 height(1.5").
