Their chassis and suspension engineers designed the S Tunes. So some arbitrary comments like "at least it HAS adjustment" is worthless to say the least. Who needs adjustment, when it is perfect? Matched and tuned shocks and springs with new, stiffer upper mounts. I trust Nissan engineers w/ tuning my car WAY over some tiny company in middle of nowhere East Asia. Seriously man, do some reading and learn how a suspension system works before you jsut say "stiffer if better" and "adjustment is better". If you have a full time race car that sees a lot of different tracks, go big time and get custom valved shocks and specially made springs for your car, but for those of us on planet Earth, Nismo S-Tunes are great!
No offense but adjustment has more bearing than you give it.
Within different courses (auto-x vs. road course) you will have different requirements for dampening adjustment for the car to be setup ideal to the driver. One setup does not work for everyone, just the same as one setup doesn't work for every road. Nor does it even work for every car.
I for instance have a car that is 13% lighter than a stock S14, prolly about 50% more rigid, and has 74% more power than a stock S14. Nissan's suspension engineers could not have forseen me doing these specific mods and designed it into the shock accordingly. So in that instance the Nismo coilovers are not ideal for my setup, and there is nothing I can do to change that.
THAT is why adjustability has it's benefits. It's simply a fine tuning adjustment thats incorporated into the shock.
Secondly, Nismo's parts are often just remodified OEM components with a compromise between road usage and spirited driving. Every Nismo part I've seen has been just a step above what came stock. That doesn't make them bad, but in terms of performance they are giving up too much to creature comforts (low noise, low feedback) compared to other aftermarket components. Basically I like to think of Nismo parts as the parts Q45Tech would design if you asked him to build you a performance street setup. Frankly while that would work well on the street, it will no doubtedly extend some of it's ability into the durability and ride comfort regions.
