Not sure I agree with that statement..Here is a question you need to ask yourself. How fast do you plan to go with this car? If it is just a rollbar I dont see the added expense of it being Moly worth the hassle. I suggest you build whatever your budget will allow for the ET you are after. You may find after pricing it out that the money spent for a moly bar will be batter spent elsewhere. FWIW my car is a Mild Steel certed to 7.50...
