For those of us who re-align frequently for different track and street uses, these requirements add significantly to maintenance costs and effort. Many of us are finding it difficult to justify the added trouble and expense, given that we haven't seen any down-side from doing it the traditional way.
None of our members has yet to visit a service department or repair shop that is even aware of the requirement. Please share with us the potential benefits of using the specified methods and what, if any, potential drawbacks we might expect from using traditional methods.
Thank you for your feedback and insights!

Ask that same question to the bolt manufacturer ARP and no doubt you'll get a detailed explanation of the different methods of torqueing a bolt.
I've heard the explanations in the past, I just can't remember them well enough to explain it here.
Basically TTY or TTA are far more precise than your normal torque wrench.
