300ZXs had stages before it was cool, us Z32 guys are car hipsters.

Back in the day, there was an accepted list of 300ZX mods/parts that put you at stage 1, 2, 3, etc. Now with everyone doing it, it's more of just a marketing technique. Back then it was JWT, Nismo, and other quality name brand parts that would put you at a certain stage in the Z world. Proven power gains and such from quality parts, now all these different performance tuner cars have so many manufacturers, plus crappy Ebay parts that you could have a stage 3 or 4 car by spending a whole $50 on Ebay lol
