Hey Moonchopper---yea, I haven't done much with Ms Scarlett recently so this thread has been stagnant. Getting ready to put a ported throttle body and catch can on soon though and will update when I get those on.
Ok, to answer your questions..
RJT = Red Jewel Tintcoat
CRT = Crystal Red Tintcoat
Basically, the CRT took the place of RJT when they discontinued the RJT for the 2012 models. So, if your car is a 2012, it is CRT not RJT.
They are both extremely similar in color. They did this so GM only has so many colors across the spectrum to use through their line of cars...the CRT is used on Corvettes and Cadillacs (I believe, but could be wrong on the Caddy). Check out this article

Black wheels look KILLER (no bias here
) on the RJT and CRT alike! I got my Havocs from Xplosive Performance. They were very reasonably priced and they fit the stock tires -- so very easy on the pocket book to convert to these rims!!

Congrats on your new ride and happy cruising!! Don't hesitate to holler if you have any other questions!!
