Hey jmarksnsx,
Hopefully I'll have some information that you find useful. Brief background, I've had a 2006 s2000, followed by an s2000 CR (completely revised suspension, re valved, damping, increased spring rates) and also added the KWv3's to the CR, subsequently going back to the OEM CR suspension. The OEM CR suspension was pretty stiff, slightly jarring, but handled absolutely beautifully. I loved how they responded to driver input. Having the KW's were extremely refined but I never felt the same response and to be completely honest, I didn't enjoy tuning frequently to get them to the same spot the OEM felt, just at a lower ride height.
Like many of us, I dreamed of an NSX for years. I'd driven all the trim levels and knew something I really missed in transitioning would be the rigidity and suspension of the s2000 if I ever got an NSX (Knowing I'd only end up with a NSX-T) Fast forward, I found my dream car, a 2002 Long Beach Blue Pearl and I knew the one change I wanted to do was suspension.
I debated quite a while on what I wanted to do. I had the mindset of keeping the car as OEM as possible but I did miss the feel of the s2000 CR. After talking to quite a few people and some independent research, I went with the 2002+ OEM Type S Suspension from the Japanese Type S, which is what SOS sells.
Ultimately mine did come from SOS, however in doing my research, what I found was the suspension "kit" is no longer offered by Honda of Japan. I don't know the truth on this, but apparently some NSX parts in various warehouses were lost during the Tsunami. The individual components can still be purchased albeit separate (strut, spring, top hat etc). After learning about the Type S revisions for 2002+, I knew that was what I wanted. I imagine SOS had purchased the Type S kit in bulk years ago and has just been selling from their inventory.
On to the review; they are perfect for what I wanted. Something to stiffen the car up some, response, and no hassles with adjusting all along keeping OEM reliability. The drop is more than a half inch, but it wouldn't go as far as saying it's an inch lower. You get a lot of "is your car lowered? I can't tell" It's subtle but enough to notice. The handling is improved substantially. I LOVE the feel. It's very similar to the CR suspension in feel and responsiveness without the rock hard feel of the 2002 Type R suspension. The ride is noticeably different as well, it is more rigid, not as soft as the OEM obviously but to me, this is nowhere near a draw back.
This review from 2008 was helpful as well; http://www.nsxprime.com/forum/showthread.php/103308-installed-my-new-Type-S-suspension
I've attached some photos to show the car's current ride height as well. If you have any specific questions, I'd be happy to go more in depth.
