I prefer the S-tune over the standard Nismo, but I like that one better than the sport package spoiler...
All we really need are two little paint matched plugs tho'...
Kind of like these
Keytechniqus Keyhole covers,Wiper plugs and Bumper plugs - NewCelica.org Forum
Scroll down at link to see the bumper plugs...
I could see about whether that Keytechniques guy would want to make some for those of us with the sport spoiler who want to swap to the S-tune... just a thought.
