Series 1
Steering Wheel Vibration
From understanding what you feel to measuring it across five vehicles. Six posts. One methodology. All the data.
Explain
01
What Your Steering Wheel Is Trying To Tell You
NVH sources, orders, FFT explained — and why tires get blamed for things they didn't do. The foundation for everything that follows.

How I Measured Steering Wheel Vibration on a Ford Escape — and How You Can Too
The full setup: accelerometer calibration, mounting location, idle measurements, highway test conditions, and data logging procedure. Every step documented so you can replicate it.

What The Data Actually Says — Reading The Ford Escape FFT
Two peaks matched the math. Five didn't. A full walkthrough of cleaning the signal, running the FFT, and identifying tire and engine orders — including the ones that don't have an answer yet.

03
Five Cars. Same Protocol. Different Results.
Ford Escape, Honda Civic, Mazda MX-5, Nissan Rogue, Nissan Sentra. FFT data at 70 mph. The findings challenge what most people assume about tires.

04
Why FFT Wasn't Enough
Introducing band-limited RMS analysis. Why the Ford Escape felt shakier than the FFT alone suggested.

05
Surface and Speed Sensitivity
What changes across road surfaces and speeds — and what stays consistent. Validating methodology robustness.

Excel vs MATLAB for FFT
Full breakdown of both tools for enthusiast-level vibration analysis. What each costs, what each gives you, when each is worth it.
Coming soon
Series 2
Tire-Road Interaction
Using OBD data and accessible tools to understand how tires actually grip the road. Coming after Series 1.
