- Jon, I read that a teardrop needs a 4 times length to width to be effective--I am trying to use a 6 to one. Now the question I don't know--do you figure 1/2 the width and that is the relationship for

- Jack's liner is a good combination of aerodynamic and downforce. When you use a teardrop you create a good aerodynamic shape but also a lift up body, in other words, you loose the downforce which you
