Q: “I’ve recently gotten a Porsche Cayman for the track, and I’m a bit disappointed that I’m not a lot faster than I was in my previous car. Sure, I’m faster on the straights, but that’s just horsepower, and not me. I don’t seem to going any faster through the corners, which I think I should be. Am I wrong? What am I missing?”
Q: Does the Friction Circle change with more speed? Do I have less grip at higher speeds than I do at lower speeds?
When looking at in-car video, how do I determine where the actual turn-in begins?
Q: “My tires have a small, raised triangle on the sidewall, near the top of the tire where the tread starts. Local legend suggests optimum/maximum tire patch is gained when the sidewall deflection/rollover/rub line (chalking tires) just touches the tip of this triangle. Is this true/false, a quick-and-dirty gauge, or totally wrong? I’m not suggesting this method, if viable, is a replacement for temperature readings across the tire. However, I’m curious because as an HPDE-only type, I don’t have the equipment, crew, and track time to properly use the temperature gauge method. I noticed that my street tires – Michelin Pilot Super Sport 4S have a tiny Michelin Man in a similar spot as the triangle on the R888R’s. So, it’s gotta be there for a reason, right? The question is: For what purpose?”
Q: “I often hear instructors talk about the “school line” versus the “racing line.” What’s the difference, and which should I drive?”
