The stock front camber adjustment area should be enough with street and semi-slick tires. You will need -3° if you go to slick tires, not before. You will like a stiffer front sway. With good coilovers, it will aslo limit the need of front camber when going to stickier tires. The front end of teh NSX being light, and even lighter if you do some weight saving (spare tire, light battery, ac delete, ...), is a reason not to go over stiff in front. In the meantime, you want the rear to be a bit "loose" to avoid any snap oversteer while tailbraking because of too quick weight transitions. All in all, good and stiff coilovers (especialy the dampers) will reduce the need of stiff sways. Same for any mod that will reduce the compliance in the suspensions (front clamps, rear non-compliance toe bushings, spherical top hats, full spherical bushings) and the chassis (Type R reinforcement bars, roll cage, ...).
I run the KW Clubsport. The KW V3 are a good street-track option. People say they can be very comfortable on the soft settings. I do not know if the Clubsport have a different damper setting but they are very stiff. Way more than what the rather soft spring rate make you think (8 kg/cm, just 2 kg/cm more than the V3). So do not read only the spring rate. Damper quality and settings is very important.
