On my 1994 NSX I currently have the Bilstein Sport shocks and Eiback Pro-Kit springs, with the perches on the upper setting and Comptech Sport sway bars. I am giving serious thought to removing the current set-up and getting the NA2 NSX Type-R suspension and Type-R chassis bars. While I drive the car everyday, the goal is to really maximize performance and the purity the NSX was designed to have. Which of the two systems will offer the best performance? Would the Type-R system be notably better than what I already have? Experience with these systems is appreciated. Also, anyone with an NA2 Type-R suspension they want to sell....please contact me.
I think after a lot of debate the general opinion is the Type-R setup extracts the most performance out of the NSX possible while still maintaining daily drivability. There are "better" setups which might be "faster" but they either cost mucho dinero ($4,000+), are very uncomfortable or both. The Type-R takes the guesswork out of searching for a great setup. It's better than 99% of all the available options. Honda put a lot of time, money and effort into creating it.
The Type-R setup is most definitely going to be less comfortable than your current setup but most that have it say can live with it, however, as Jim mentioned, there have been many stories of people finding it too uncomfortable for DD and removing it. The point is, be sure you know what you're getting into before going that route.
One important note: if you're not tracking the car, you probably won't be able to take full advantage of what the Type-R setup has to offer.
If you're not tracking frequently I would really recommend the Zanard/Type-S setup. It's more comfortable and isn't overkill for the street like I think the Type-R might be. You'll notice a vast improvement over your current setup especially with the addition of the Type-R chassis and sway bars.
A cheap, effective alternative would be retaining your Bilsteins and adding Zanardi springs, Type-R front sway bar and Type-R chassis bars. Both bar kits don't compromise the ride at all and the Bilsteins should be able to handle the Zanardi springs.
There are several coilover packages which appear to give Zanardi-like performance and have gotten very positive feedback (SOS, JIC, Tein) but cost is a factor. The Zanardi springs (~$325) over your existing Bilsteins with the two bar kits (~$240 & ~$135) will be very cost-effective and really make a difference. It's a drastic improvement for less than $1,000 installed. You'll easily triple that figure if you decide to go with coilovers and the other items.
Another option would be NA1 Type-R springs but the Bilsteins would probably not be able to handle those rates effectively. That setup falls somewhere between the Zanardi and the NA2 Type-R.
