man, i wish i had a c6 just to help you out, but i have no idea. my install wasn't as bad as that. mine needed a little convicning to meet together below the air bridge and the air scoops fit like **** where the fog lights are. but they are riveted into the fog light bezels no there isn't any adjustment after the bezels are bolted in.

 

i LOVE my vararam.. gives ENORMOUS gains on roll races on the freeway and high speed runs. (i pull liter bikes no problem on a measily 100 shot hehe) the fit/finish isnt the greatest but then again the performance has no competition, these intakes WORK, and they work VERY well!

i LOVE mine.
