Exactly...Sure, it's just math but things like the travel of the front suspension and steering, tire deflection, the effects of alignment specs and how they change with compression of the suspension and steering, etc. isn't obvious to everyone and it's not as simple as just getting a tape measure in there.
I appreciate that someone with first hand experience, patience and the ability to explain things to people without making them feel like an idiot, is willing to share their knowledge and time.
