As stated, stock on the SS/TC's (both coupe and sedan)...expensive from a dealership and good luck finding someone who will sell theirs. Also, they are 5x110 lug so if you have a 4-lug, forget it. I would love to have something similar to these, but oh well. Then again, I'd love to trade my car for an 08/09 SS/TC sedan...won't ever happen....I'm too lazy to drive a stick for one thing...for another I don't want a larger car payment and to extend it out any longer.
