I installed the air suspension myself, I have some experience with other types of suspensions but not with air, the purpose of chossing OnAir were because the Model 3 is a lower car and the bumps in Mexico are crazy so I need a suspension that help me to pass them without damage the car and could lower the car to look awesome, you can confirm it with my picture, after I installed I had some issues with my experience, not with the product, so Tom helped me always and after check some tips with him I could finish the setup. Thank you very much for your help Tom, many congratulations to your team.
