How To Analyze Your Steering Trace In Data

What are some common issues that our coaches find in steering trace data for racecar drivers?

  1. Turn in rate: You will see the red line in this video, the driver has a very fast turn in point. We see this by the linear increase at the turn in point of the red line. We can see with the white line. The driver slowly starts turning. This lets the weight transfer slowly. Then once the weight is set, the turn can be more aggressive.
  2. Using lateral G when you don't have steering in your data: You can see here that with lateral G, we can get a pretty close proxy for our steering trace. We can see where we turn in and where we start to unwind the steering wheel. But we can't see if the car has oversteer or understeer or exactly how a driver is manipulating the steering wheel.

About the coach

Colin Mullan

2020 GT4 America Champion

Car Racing

I’ve been racing nearly my entire life, with experience in everything from open-wheel racing, touring cars, to GT and prototypes. In 2020 I won a GT4 America Championship driving with Andretti Autosport, and have been recognized as one of the most winning drivers in GT4 racing in the US. My goal as an instructor is to teach you the “how and why” to improve as a driver. It’s easy to tell you what to do to be faster, but becoming a better driver on track takes more than that.
