AX street tires vs cup tires

[harryrcb]

I was afforded a unique opportunity to test how much difference, if any, cup tires would perform at an AX event compared to street tires. I was asked to help design and setup an AX course for our Sunday event. I ran my street tires on the setup day and after a couple of laps did a consistent 46.5 second run. at the event on cup tires I ran a 44.2
A beautiful day at Zepherhills Air Port with a good turn out of participants. I believe we had 40 drivers and a variety of cars. Unfortunately for me, I had one of the top dogs run in my class who even took first overall with a 42.2 (beating our national champion) but I took second in class and in the top 5 overall. the total scores did not get posted yet but it was fun anyway so here is one of my faster runs and one practice run where I did not do so good.
