Put EP3 wheels on awhile back.

fogs some time before that:

Since it came with Honda Access suspension, I fitted an OEM front strut bar:

Nothing special to you guys, but replaced the rear bar with a JDM one. If you look at the previous picture you can see the AUDM bumper which is three pieces and was coming apart.
So rear stickers are gone, although I still have the old bumper. Car is going good. Almost 50,000km on the clock now.
Not sure about the wing, but since the car came with JDM Honda Access suspension and muffler, I guess it could be JDM.
US definitely has pace/safety cars. There was a matching (colour wise) NSX that they shipped from the US. Also plenty of Corvette, etc. ex-pace cars available I would imagine. Which reminds me, I found a local mag featuring my car along with a yellow 3.5L supercharged yellow NSX safetycar.
