Near-stock suspension upgrade question
Now that I've had the car ('07) correctly aligned, it's really come together. NOW it feels mostly like the car it should.
But, I'm still a little bothered by the slow speed damping in the rear. If anyone's read my comments before, it's mainly large pavement heaves or dips that upset the rear while in a turn. If the pavement is smooth, it's pretty good.
The thing is, I love the high speed damping on all four corners. To me, it is not too brittle; it is pretty much perfect.
The ideal setup would be coilovers that maintain something very close to stock high speed damping, with front low speed damping close to stock, and rear low speed damping firmer than stock, with possibly a firmer spring rate. They don't necessarily have to be adjustable, but then the valving needs to be correct out of the box.
I'm not interested in lowering the car any more than is absolutely necessary to get the suspension to work correctly. I don't want to throw off the roll centers nor do I want to have to correct bump steer or control arm length issues with yet more parts. The only other reason for coilovers is to be able to corner balance the car.
Controlling dive under braking and roll with the coilovers would be a good thing too. If I were to quibble, the car could remain a touch flatter.
Any ideas? I've done quite a bit of reading on the boards and so far haven't read about a solution that sounds like it's 100% for me. Based on reading and personal recommendations, I'm leaning towards PSS9s, but I worry that they're smoothing out the high speed damping a little too much, which most people seem to report as the case. The KW v.3s I run on my other street car do this too. As I said, I love Honda's valving in this regard.
Would it be crazy to install stiffer rear shocks and springs from an AP1 S2000?
Anyone who's got some deep insight into multiple suspension setups for these cars please chime in!
Thanks!

Hmmm...unless it's something super interesting, try to keep your posts concise and short. Not trying to be an ass, but I got bored half way in and clicked back. I then felt bad and came back to leave you this message.
Someone posts a clear, articulate, detailed question, including all relevant information, and gets flamed for prolixity rather than applauded for not wasting the board's time with the incomplete or incomprehensible drivel that seems more and more to dominate the forum. Very nice. The sound bite generation's attention span, or lack thereof, is truly frightening.
Pieter, I'm sorry I don't have an answer to your question; I just wanted to offer you some support. I hope someone does give you the answer you deserve.

To the OP: I dont have enough first-hand experience to help, and any second-hand experience I might offer, you sound like you already have. Good luck and nice post.
Not a lot of help, just a couple quick notes:
The S2000 suspension is set up with a fair amount of anti-dive (and I think anti-squat, too). Keep this in mind when considering a stiffer front-end. I guess this is a little obvious, but consider anti-roll bars if 'flatter' cornering is one of your chief goals.
Anyway, onto the bigger issue- is your complaint going to be solved with a firmer rear end (shocks or springs)? It doesn't immediately sound that way: It sounds like your issue is the rear is unloading during steady-state cornering, upsetting the balance. Any increase in stiffness is going to make that transition faster, not slower. It almost sounds like you want to reduce the damping on low-speed droop.

Shrike and tjberry_1 thank you. You both understand.
Given the tone around here, maybe next time I'll just post yet one more thread like the dozens and dozens I saw when I searched entitled "Which coilovers should I get?" with the addition of "how far can I drop it?" in the body. I'll look forward to the abuse that ensues for not qualifying the question.

You seem smart and may have researched, so I'll ask you this - When does one need axle spacers and a bump steer kit? I see so many lowered S2K's on here and wonder if they all have corrected the suspension...
