Since I added the two small carbon fiber vents, I found a supplier that has very high quality vents made with aluminum. I installed Trackspec vents on my C5 and love them. I got with them to make one large vent for my Camaro. I installed it a few weeks ago and I really like it. Next week, I will be running the car at the Optima Search of the Ultimate Street Car event at Charlotte, North Carolina. Hope to see you there.
