Yea, I just don’t like the design of the oem 15/16. IMO, it makes it look old. On the Dali/Bilstien set that I found, seller told me he bought it new two years ago. I was planning to have Autowave reparable NSX mechanic in CA. The mechanic told me I might want to think twice? Dali springs been out of production for 10yrs. He said if the car sat for 10yrs on it, springs will sag. He told me to get the Swift springs(budget set up) or KW V3, but the wait is months. What your thoughts? I’m a bit confuses, who’s right? Or is Autowave just trying to get deal done themselves.
Well, honestly the car is old . . . LOL.
With the 15/16 at factory ride height you have the look of a 4x4. It doesn't look great. Drop it down .8" in front and .6" in the rear with the Swift springs along with the wheel spacers and the stance looks much, much better.
BTW - you'll find the ride with the 17/18 to be harsher due to the narrower side wall. Plus if your streets are a torn up mess those 17/18 could get bent when hammered in a pothole. I'm probably beating a dead horse here but want you to be fully informed.
OK - back to the springs. Hard to say whether a 10 YO spring will sag or has already sagged, but if it was me I'd pass on any used spring. The cost differential is not that much between new and used and honestly who wants to replace their springs twice (2x the labor costs) because the first set sagged. One of the pluses with the Swift springs is that they are progressive. This will give you a better ride than linear springs but still have the handling characteristics you are looking for.
The KW3 are also a great solution and would give you the ability to adjust your ride height vs the fixed length Swifts. The KW dampers are also matched to the spring rate which is a plus. Obviously cost ($2,500+) with the KW3s are a big consideration and honestly unless you are serious about getting into HPDE days the adjustability of the KWs is kind of overrated. People will say you need it but once the rebound and compression are correctly set for the street you'll rarely ever change it. While I don't have KW (I have MCS) people who do have them love them.
One word about lowering; lower is not always better. Yeah there are owners out there who have their NSX slammed to the ground and to some it looks cool. I can tell you from first-hand experience that lower is not better. You'll tear up (or tear off) your front spoiler (which is NLA from Honda BTW) and also rub holes in your fender liners (I did) under compression. Handling is compromised and every speed bump and parking lot entrance will present a challenge to your front end.
If you go with the Swift springs definitely get the 1997 NSX dampers. Even though your car has 20k miles the valving is not ideal for the higher rate Swifts and your ride quality will be compromised. Swift springs are in stock at Vivid Racing

I don't think you can go wrong with either option (Swift or KW). It really comes down to how much you want to spend. The end results are going to be largely the same.
