FF Tire Discussion: How Does It Affect F5?

There is a discussion occurring in the FF group about implementing a harder tire rule for FF is SCCA. Options mentioned have been R45s, R60s, and DOT tires. All of them would affect the cornering speeds for the class, to varying degrees. Since your class is typically on the track with us, you are stakeholders in it, too. How would you feel about it? Do you think it would help or hurt the run groups?
