i guess someone will have to find the final drive ratio for the two cars, also tire and rim sizes (stock) and then just compare the cars. If you keep the same rim size, just getting a thinner tire helps? such as low profile, which the crossfire pretty much has already? i'm not real familiar with the tire and rim aspect of cars as far as the technical and performance aspect goes, that's kind of why i posted it, just trying to learn new things thanks to all that have replied.
