That is not ztune. why not? #1 z-tunes intercooler says nismo on it. #2 the
z-tune has brembo brakes not ap racing. #3 the z-tune has a thicker
titanium strut bar that says z-tune on it. that is a standard r34 gtr strut
bar. #4 the z-tune has red and black leather alcantra interior. #5 the
z-tune does not have mine's carbon mirrors. #6 the z-tune has flared
fenders over normal r34s. #7 the z-tune has a prominent oil cooler behid
the rear diff. this does not. hope that helped. :)
