Race Ramps VS C6 Corvette Base 

Race Ramps VS C6 Corvette Base I tried the 67 inch race ramps and the air dams on the 2007 Chevy Corvette C6 base model hit the ramps, Then I tried the 80 inch race ramps and they hit the air dams as well. You will need the 67 inch race ramps and the extender ramps on top of them and then they are suppose to clear it. I can't tell you for sure because I got tired of buying stuff. I can tell you it hits these two size ramps for sure.
