When you fix your bungled tire situation don't buy cheap rubber.

Wahoo! Neat toy!

I haven't yet had to use sunscreen this year.. weather has been incredibly mild so far. *shrug*...

The S2000 community in general seems to be filled with a ton of enthusiasts, who seem very personable and generally pretty nice. I give the wave to other S2000s I see on the street, and 90% of the time, I get the wave back. Usually the remaining 10% had their tops up

As the miles add up, you'll just like it more and more.

Heh. I was actually getting a little frustrated with my R6 because of my unwillingness to push on public streets, and my inability to get to the track frequently enough.

89mph in first gear is fun, until you realize that you cant open the throttle for more than a few seconds in ANY gear without exceeding a significant part of your saftey margin.

I have noticed that the transition to oversteer in the S2000 is rapid, but it feels very controlable. I've noticed two main handling traits that make it differ from my previous car (s13 240SX), or any of the other RWD sports cars I've owned.

Firstly: the car doesnt seem to actively correct steering lock in an oversteer situation. With both my RX7 and my S13, once the rear end began to rotate, the steering would automatically begin to feed in opposite lock. Balancing the oversteer was simply a matter of smooth throttle and catching the wheel at the angle I wanted to hold. With the S2000, I have to actively countersteer for anything but the slightest oversteer. My admittedly limited knowledge of alignment tells me this has something to do with trail at the front wheels as a result of caster angle?

Secondly: in a corner, after the chassis takes a set and power can be applied, after applying power it feels as if the tires' slip angles change. I get a sensation of the car's line tightening without any actual change in chassis attitude. Would this be the LSD beginning to transfer torque and push the car around the corner? I know the S2000 has a torsen unit. I only have experience with viscous-coupling LSDs which are very progressive in their engagement and tend to require actual wheelspin before they act.

Any thoughts?
Well, I gave up bikes 18 years ago, when our daughter was born, and the thing that made that essential was that I am all too willing to push hard on public roads. I'm extremely careful about when and where, but I tended to ride as hard as the conditions permitted, almost constantly. At that time there were no venues for bikes in this area, so deserted back roads were the only place we had to enjoy the machines. Hahaha, I got a ticket once for doing 98 in a 45. I won't say I was totally innocent, but the judge threw it out because it was bogus.

I go through back tires on my S2000 at about the same rate I use to go through back tires on my superbikes.

As for the two issues that you have with the handling, I'd advise getting the tires and alignment sorted out before drawing any conclusions. Tires and caster (and alignment in general) affect steering feel, but with S02's and good alignment the S2000 steering *may* still leave you wanting. When the back tires are spinning the EPS gets confused (because it is speed sensitive) and steering feel is all over the map. It also has limited lock (compared to some other cars), so you reach a point in a drift (or spin) where you just don't have enough lock to countersteer enough (the point of no return). I'm not really sure about how strongly the steering self centers, because it's never called attention to itself, but you may just be feeling the EPS get squirrelly when the back tires are spinning. I think I may actively correct for oversteer habituallly, so you may have noticed an issue I've overlooked. I'll have to play observer and watch what I do next time I'm out sliding the car around, because I'm not really sure. I know that once I'm sliding a lot of the directional control comes from the throttle.

The slip angle of the tires does change when you apply throttle. This is true with any car, but with the S2000 you can feel it more readily than with some other cars. Anytime you apply thrust to a tire its slip angle changes. I think your tires are probably producing some screwed up thrust changes with the applicaiton of power, so I'd suggest a reassessment after you get the tires and alignment sorted out. You'll still see thrust effects, but they'll probably be more of what you expect. The car is near neutral in steady state cornering, so acceleration or deceleration changes the handling bias, which changes the slip angles of the tires, which in turn changes the turn-in. Tires, alignment, and smooth inputs, will (probably) make it a non-issue.

My factory alignment was horrible...killed the stock bridgestones in a matter of months.
