How would you run a lateral acceleration test in a vehicle at slow speeds
from 20mph to 30mph on twisty roads and at no more than 40mph?

The issue is discussed in this repair thread:
o Clare - are smaller car tires easier to balance than SUV tires?

Where I picked up a free graphical tool for testing acceleration:
o Sensors Multitool, version 1.3.2, by Wered Software
<https://play.google.com/store/apps/details?id=com.wered.sensorsmultitool>

Where there are two types of acceleration graphed
o acceleration
o linear acceleration

Where I'm not sure yet how to construct the test experiment:

Since what I want to measure is
o lateral acceleration

Any advice for how best to set up the measurement test?
