Suspension modification is by far trickier and more involved than adding hp.
When I put Tiens on mine (I used RAs) I spent $2000 on suspension tuning, alignment and corner balancing on a chasis dyno. It's not just camber and spring rates.
Once you change the spring rate, or valving of a shock it will interact differently with the tires you're running & sway bars etc. That's why many guys bolt on good parts, and have a firmer ride, but their car actually pulls fewer g's and they run slower at the track. This happens all the time.
The NSX-R is a great solution as Honda did all the research for you and you just need to bolt on the R sway bars as well and job done.
My former NSX was so planted and neutral. It gave me massive confidence at speed, and after driving others with more expensive parts, but no tuning, just install, I could really see the difference.
Your best bet is to talk to Chris at SoS or someone else who is exceptionally knowledgeable for setup (rim size changes things to). Then have it installed at a race shop that knows how to set up suspensions properly, not just bolt them on to a preset spec from the coilover manufacturer.
You should get Stuart involved in this to. He's Red here on Prime, and he's seen it all from an instructor's point of view on the track when it comes to modded suspensions.
----if you just want a lower ride height, there are springs that will give you that while maintaining the overall spring rate. So your handling won't be adversely affected and it is a plug and play solution. Red did this to his 02+ and it's great.-----
