I have an SVT Focus street car so this discussion has been interesting.

At the NASA championships a couple years ago at Mid Ohio, the fastest lap time recorded in Spec Focus was in the 1:48s. (Do not know if they ran the pro course or the chicane.) Does anyone know what the lap time of such car might be if run in IT trim?

In order for the car to be a world-beater in ITR, the Focus would need to run 1:41s on the chicane configuration. In ITS, maybe 43s.
