You read what I wrote at all? I said the aftermarket stuff is better by far in several ways. I also said that they are designed for handling, comfort, modern handling and direct bolt in ease. Better at 9/10 things then torsion bars. Extreme drag race application is outside of the norm. As for aftermarket suspension not having any engineering? I can confidently say they have more time engineering the suspension then you had in your ignorant internet tough guy response.
