Don't want to start a "holy war" about what is or isn't "autocross", but I don't think 90 mph is autocross material. Not saying it isn't fun... it's just not what autocross is.

Even the BMW club's website says that "speed rarely exceeds 65 mph". From the reports here of at least the past two events they've done at Brooksville, this does not appear to be the case.

Feel free to discuss... or not. I'm just pointing out the obvious.
