Have you ever been to a track day or HPDE with your S2000?

 

^ that would be my advice too.

Getting some instructor assisted track experience will help far more than any CO's.

 

I feel that the stock suspension is a bit on the harsh side. Will coilover make my ride worst or better?

 

If your car feels unstable at high speeds you should get your car aligned. My cars is firmly planted even at 130+ mph.

 

That depends on the coilover brand. The adjustable Bilstein PSS9s will lessen the harshness of the ride, even when set on their firmest setting. Recommended!

 

I havent had a chance to hit the track this year. I took the skip Barber driving class last year (The first year I had the car) Now I want to mod because i have the money too. I might not have the money in a few months when the track open up here in new york and connecticut. I do intend on tracking atleast 2 possible more if I have more free time...But like I said Handling is not the only reason I want a suspension setup. I have had 3 alignmets and on the way back anything over 80MPH the car still doesn`t feel safe the rear end is just to touchy ...I have new OEM Bridgestones so I know thats not the problem. I feel if I stiffen things up it will help a lot more....I want something that will compliment my next few mods thats I have listed....I will be adding 4.57 gears aswell as a flywheel and a ACT clutch to the mod list I have already.

 

I went with Koni/Ground Control, an excellent purchase IMO. Definitely handles better than stock.
