Good advice on getting some new tires check out these new shoes!I agree about time spent racing autox vs road course track days. Here locally we have other clubs than just the SCCA. They allow us to take our runs almost back to back, keeping tires hot and allowing us to get our driving over quickly. I usually work the first heat and drive the 2nd, then go home.
That is definitely a slow course for a big car. I highly recommend tires to increase the fun factor on slow courses.
