Honestly, if the S2000 feels unstable at 70 going around an Interstate curve, I'd make sure the rear wheels are actually on the rear of the car and you don't have any spring spacers in. What size tires do you have on your S anyway? Do you have any aero effects on the car?
How do you know or how can you check if you have spring spacers on?

I don't understand why lifting off the throttle around turns makes you spin out. It seems like gassing through corners would upset the traction of the car right? Can someone explain this to me?

When you lift off the gas, you transfer weight from the rear to the front. Since you have less weight in the rear, you have less grip in the rear. It makes a wider turn. Since you have more weight in the front , you have more grip in the front. It makes a tighter turn. When the front is making a tighter turn than the rear, that's oversteer.

To Saki GT fr NOLE67 --I bought my 05 SK2 used with 14,500 on it. Have no idea how it was used but it appeared in mint cond. It has General Exclaim UI-IP ? , 245-40-ZR 17's on the rear and BRIDGESTONE Protenza RE050, 215-45-R17's on the front. Don't know if it's relevant or not, but there's a window sticker that reads Falken DRIFT.
Okay, first of all, you have different tires on the car with different traction characteristics - buy some quality tires and get them on the rear pronto - RE050A PPs would be a good choice, but having mismatched tires is dangerous.

Second, I don'y know why there's a drift sticker on the car, but maybe whoever owned the car before you drifted it and has a very stiff rear suspension - that would also explain the mismatched tires. I'd make sure the rear suspension is stock.

As for spring spacers - look in the springs. The spacers are big blocks that slide into the springs and keep them from compressing.

Yea, and RE050s are the original OEM rubber, but RE050A Pole Positions (PPs) are a better compound and tread.

Thanks to all the responders. I've had the alignment checked. Toe was off a little both front and rear. Now in spec and we'll see if that makes any difference. Although tires may be mis-matched (brands), I've got too much tread on both front and rear to scrap. I'll just take it easy on the interstates until I buy new rubber. Based on reviews, the Goodyear Eagle F1 GS d3's sound like a great ride. Again, thanks for the help. By the way, I've been to both the Panoze school at Road Atlanta and the Petty deal at Lowes Motor Speedway, so I have at least an elementary idea of driving a car. Thanks again.

I just came from a gti and yes i feel the same way as you. My gti had a suspension setup and while the s2000 handles way better, for a long high speed turn (on a public road) fwd is better for novices like us. I mean if the tail spins, i doubt i will catch it (ap1 also).

What concerns me coming from german cars is high speed straight line stability. Some here might argue the s2000 is great, but its imtimidating to me as cross winds affect it greatly. Wonder if front lip and rear spoiler will help it become more planted.

Thanks

If you go fast enough, the rear end gets quite light due to aero lift.
