Ok OAK, you're gonna hafta be a bit more specific...
Were you under the impression that all R32 GT-Rs except the V Specs came with color-coded lower front lips?
Also, the "drift type" rear spoiler? I guess you're talking about the little Nismo bootlid extension under the standard R32 GT-R rear spoiler?
Well, ALL R32 GT-Rs and V Spec I/IIs came with unpainted matt black ABS plastic lower lips, Nissan only painted the front bumper proper, not the lower lip. It's just that some owners paint the lower lip body color sometimes.
About the little bootlid extension, it came standard on the R32 GT-R Nismo. For the most part though, I think those Nismo bootlid extensions are just a generic copied item that some owners put on randomly... except for GT-R Nismo models of course.
