Ask Ross: “What happens at the contact patch when steering is applied during the first few rotations of the tire? Is there a momentary increase in grip at the rubber-pavement interface? Does Alonso know something? Or am I chasing unicorns here?”

Q: How does endurance racing work?

Q: “How do I adjust my optimal turn-in and braking for an off-camber corner to minimize understeer?”

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?”

Q: “I’ve never driven on a race track, but want to, and found your website full of great information. But since I’ve never been to what I understand is called a “track day,” how much will one cost me? Also, how should I prepare to do one?”

Q: “I am an instructor and often suggest to students that they review your Virtual Track Walks in preparation for a DE day. They have asked me, “What does he mean by “collect up” the car in turn 2? As you will recall, there is a discussion of racing ovals and using a “diamond” line. We teach either the single apex or a double apex approach. I can’t explain to them what you mean by “collect up.” When we teach double apex, we are taking a relatively fast, straight entry, braking to apex 1, releasing/rotating and driving to apex 2 and tracking out to the right side of the track. Perhaps the double apex approach with braking to Apex 1 and then turning is the same thing as “collecting up”, but I’m not sure.”
