I too like to drive on the edge, which is why I moved from the Boxster to the S2000. You haven't lived unless you have had the backend step out on you round a high speed corner, you soil yourself slightly and then bring it back in line.

No better.

 

I drove the '03 for a about a month and now have an '04. I can honestly say that the '04 is less biased toward oversteer, although this is still its default set-up. I found the '03 a bit twitchier also. However, I don't think this is that big of a deal especially if you decide to mod the suspension anyway.

I do like the 9000rpm redline in the <'04 though, especially on quick auto-x courses where shifting into 3rd is simply a waste of valuable tenths.
