7. Ackermann has been discussed a lot in the pages of CT, but for a very good reason. It is critical to how your car will turn the corner. Excess Ackermann can cause a push that can’t be corrected with the usual setup changes. This shows how you can use a string pulled alongside the sidewalls of your tires and extending out ten feet from the hub to measure Ackermann. It is quick to do and accurate, not to mention cheap.
