C6 Z06 brakes are a big upgrade for a C5. 6 piston front calipers and bigger rotors. 4 piston rear calipers and bigger rotors. Requires 18" wheels up front.
They look good on the website. They look better than the "speedracingturbo" c5 headers on amazon.ca (also cheap, $300 for headers, $300 for off road X).
You should try them out! And let me know if they fit haha!
