How to Test
Setting out to modify your car’s aerodynamics can be daunting. Where should you start? What should you do first? What changes will give you the most bang for your buck?
The first thing you should do is identify your goals. If you don’t have something in mind you want to accomplish, you can’t plan out a way to get there. And the more specific you can be about where you want to end up, the better ability you will have to make effective modifications that accomplish your goals. Take some time first to identify these. Then, make a testing plan: what changes you want to test, how you will test them, and what you will do if the tests are successful or not. This plan can change as you go along (my plans change every few weeks or so as I finish more testing), but it’s important to have something down on paper so you have some direction.
Test Effectively To get trustworthy results from your tests, you will need
to control as many variables as possible. You have some influence over these
both in how you plan your testing and how you carry it out.
