Just an FYI guys, the $199 version is not the same as the $115 version.
Here is my personal experience with both products.
The $199 version is made completely of carbon fiber so it is light and strong. It mounts through the front grille and is easily removable. With the plate off, the car looks stock and you can't see any mounting hardware.
The $115 version uses a heavy metal track the mounts under the car, which can easily scrape on speed bumps, parking curbs and road inclines. When you lower the plate, it slides under the car thus further increasing the chance of bottoming out. You can see the plate tucked under the car and you can see the mounting hardware. I had the $115 version first and the sold it and purchased the cf version for my ZR1. When I get my C7 in the spring, I will purchase the Carbon Fiber version.
