It depends. Have you done it on other cars before? If not, then it's better to have someone else do it.
It's not as easy to put on suspension on the NSX as other cars, but it's not impossible either.
You do have to take more car when putting them on this car vs other cars. The parts are not cheap if you make a mistake and most of the parts are aluminium. Biggest mistake most people do is ripping their CV boots when installing the rear suspension.
