So let me get things straight,
an s2000 without VSA will have the same slipping point where the car will lose grip and begin to slide in a turn as an s2000 WITH VSA assuming all other variables are exactly the same? the only difference is when the s2k without vsa starts, it will continue to slide unless corrected by the driver technique and the s2k with VSA will activate VSA and either distributes braking and/or cut off throttle in order to correct the problem from getting worse?

Some folks will argue that a great driver can always do better than VSA (or whatever term) can. I dispute this.
If a VSA algorithm can individually (or even front vs. rear or left vs. right) control brakes or power, it can theoretically help even the best drivers, unless we have 2 or more brake pedals and 2 or more gas pedals in a manual setup (silly I know).
VSA (if it's designed right) can change the loading of each corner, where we can't.
I'm not saying it's perfect, but it can be an aid to even the best drivers in the worst conditions I believe.
My ignorance is what the S2000s VSA algorithm and control is. I don't know the specifics unfortunately.

actually, if the VSA is pushed too hard it will even began to slow the car down by braking and adjusting less fuel.
ex: (did this yesterday) i was trying to see if i could chirp 2nd with my CDV, and most say they cant. i hit the rev limiter in first slammed in second and let the clutch out hard. i know, i know, just trying to see if i could. and man my tires spun enough to let VSA kick in and slow the car down by adjusting less fuel. FWIW, this was done on a straight road and after 30 miles/33 min of driving on r-s2.

Didn't you learn your lesson after your first wreck?
And the VSA in that case might not slow you down. It slows the engine down so the rear tires can regain grip, but that might actually be faster than spinning your wheels. The best acceleration is between 5-10% slip.

"oh, VSA allows me to slips a little" so i gas it a little thinking thinking im about to over steer a little. NOPE!!!! i see the VSA light (!) and my car goes STRAIGHT!! i understeer right into a curb. let's see, i bent the front passenger: stock, upper and lower control arms, i broke the knuckle. the rim was dragged under the car and was jacked up.
so, the moral of the story, vsa is great but will not correct really bad driver stupidity. next time that shits off!

ok so let me get THIS part straight then,
so i'm going to say that the majority of us agree that an s2k with VSA is more safe for the street than one without. Now, an 06 s2k with the VSA OFF will be exactly the same in terms of handling and everything else and not more safe or less safe than an 05 s2k that did not come equipped with VSA, correct?
and thanks again everyone for your input!

That's not VSA. That's traction control. VSA corrects over-steer and under-steer. It will not engage driving in a straight line.
