I use the S2000 as a daily driver and like to go to Sandvoort or the Nurburgring too.

Which upgrade do you suggest to make the rear more stable?

Springs?
Other Mods?

 

Try an X-brace.

 

For rear? You need a wing

 

For this model year you can upgrade the lower rear control arms to reduce rear wheel deflection. This will settle the back end.

 

buy a bigger front sway bar.

 

When I had my MY00 I ran a cusco front sway bar and it made a huge difference. The X-brace didn't really make a difference as far as settling the rear end down.

 

Concur. Couple that stiffer front sway bar with a UK 4-wheel alignment and you'll be surprised how much firmer the rear end feels planted. Mine is set up that way using a Whiteline #BHF48

IMO rear spoiler/wing , or less agreesive alignment and agree with the bigger front swaybar.

 

You can instruct me?
Pictures?

 

I installed the "Go Fast Lab's S2000 anti-bumpsteer rear control arm kit". This kit adds a heim joint at the end of the lower rear control arm to reduce rear wheel deflection. The difference was amazing. I don't know if Go Fast is still around, but, I'm sure that someone still makes these. Google to check where you can find these.
