those have obviously less agressive bolstering than the recaros. Nismo doesn't make seats by the way. People put the nismo logo on cheap crappy aftermarket seats and jack up the price. The recaros in the '99 Z i'm pretty sure are the same seats that are in the Evo. You can occasionally find someone who is prepping their car for racing on any of the various evo forums, and i've seen their stock seats go for under 500 bux for the PAIR. That would probably be the best bang for your buck seating upgrade that I could think of...
