What are you saying the contis are better then?
They may be a good tire, but I doubt that they are better then the Crossfire's optional Pilot Sport 2's for summer road and track use.
There are all kinds of wheel and tire options for the Crossfire, Im having a hard time picking what I want because there are so many choices.
Have you ever been to
www.crossfireforum.org ??
There are alot of members there with aftermarket wheels/tires.
