A major reason I have seen for tramlining is type of tires combined with road surface... did you change tire size? I know this sounds stupid but think about where and when you have had this problem. Could this problem be new and intermittent because you have new tires on some occasional varied surfaces?
Another issue I have seen is the wrong tires mounted on the wrong wheels... front / rear confused. Too wide a tire in a narrow rim can feel the way you describe your problem.
I know I used to really be prepared for severe tramlining when I had my track tires mounted and drove certain roads with smooth but very uneven surface.

My car is an '07 with everything stock (except tires i guess). Is there a way to verify I have the right wheels on the right spot without taking it to the shop? Not that taking it in is a problem, but I would like to verify it myself if possible.
Also, I will post my alignment spec numbers ASAP and thanks again!

Isnt road tracking a common issue with the s2000? Is your car lowered? I have the same issue on the highway, feels as if the car is yes, being pushed by wind or following grooves in the road. Which is why im ordering the t1r anti bump steer kit. Here's Evasive's description on the product;
Do you ever notice how your wheel tugs when driving over un-even roads or at high speeds on a lowered S2000? The angle on the steering tie rod has changed due to the lower ride height from coilovers or lowering springs..etc. The factory has designed the steering system to be optimized at the stock height. It takes very little angle in the wheel to make the car steer. The T1R bumpsteer kit returns the steering tie rod to the more optimal and to create stock-like suspension angle.

Just had this problem a few months ago... I bought a set of tires for the rear and it was completely unstable/any steering input was way squirely and felt like the rear was going to slide out... I couldnt even take a turn at a posted speed limit sign it was that scary... anyways it ended up being a set of crappy tires and I bought new ones for the rear with a stiffer sidewall and a higher rated tire... if your tires have different speed rating or to low of speed ratings then that is probably why... get new rear tires and make em sticky... s2000's are picky about tire choices...
EDIT: it has nothing to do with your suspension... I will promise you that for sure... I know the feeling and it's the most scary feeling in the world....!!!
What tires are you using...? Take it back to the tire shop and tell them you need to have different tires... it's completely unsafe to drive under those conditions....

I first tried the Hankooks V12 Evo, all four, felt the same. Then went with Mitchellin Super Sport Pilots all four, same issue. I will take my car again to check for any balance issues etc, but at this point I'm not sure it will be the tires (altough I do prefer it to a suspension issue)

Yes. the toe may be a little low on the right rear during alignment #2.
But I dont think its enough to feel what you are feeling.
you say you got a flat. Are both REAR tires currently the same size, brand, age, pressure and wear? Do you have any side pull under acceleration?
