Hi Marc,
While lowering your Vette I would also suggest a few other mods. Go check out RPI on the links below. A painted Z06 spoiler and door handles would look sweet with your color. I did this mod as well and the visual effect is so much nicer. Your not really changing anything so it is still pretty much stock. They have sells all the time so check them out. I also added a painted GM grill which is also a very nice touch.
Anyway, good luck with your lowering job.
Greg
