flathead,

Just an idea... do you think it could be caused by the "crown" in the road making it pull ever so slightly to the right? Different roads have different slopes, that's where I've experienced cars drifting or pulling to the right.

Another thing to think about... the Xfire has a well tuned suspension and I'm thinking that just the slightest crown would cause the car to pull or drift. I'm not a suspension pro so it's just a guess on my part and I wouldn't get too concerned unless your tire wear gets way out of hand. :wink:
