How tragic to have to do that to your new C6! For fear of sounding real anal, I will have to say that my dislike for a front plate stuck on the front of a C6 will keep me from owning one. I'll go with the C5 thank you!
I was recently involved in a live forum with corvette design and production personnel at Effingham last weekend. This front plate question was first up from the crowd. You should have heard the lame excuses from those guys.
GM seemed to think it was no real problem in states that require front plates. An engineer said something to the effect, "Hey, no problem. Your dealer will just attach the plate frame to your front end with absolutely no drilling. He will attach foam sticky strips and put it in place." The next question from the crown went something like this, "And how do we remove the plate bracket when we go to a show?" The response was something like, "All you need to do is take a hair dryer to the attaching points and just peel her right off." Yea right! I'm going to do that every other week.
The engineers did caution against blocking any of the air intake with a make-shift plate frame because the C6 is going to need all the cooling air it can get. Probably especially in Z06 trim.
