I have a pending race coming up sometime this spring with a local friend of mine that bought my old Spirit R/T. Wanted to know what you guys think will happen.. I have driven both cars and tend to think the Caliber will be losing. They are such different animals it is hard to tell though. I rarely lose races in the Caliber on the street. The last one was an '04-ish Corvette Z06 and he just tip-toed away..
