Just playing devil's advocate for a minute here... what makes you think that that particular engineer has it right? If you ask ANYONE who had FRPP FR3 dampers for instance, how much better the car works with Koni's, or even D-specs, you'll understand real fast that just because something says "Ford Racing" on it doesn't mean that much.
I am a 'true user', I ran a Shelby GT for 3 years, I'm intimately familiar with the FR3 suspension, also stock GT and V-6 stuff (had a '07 GT as well as my '11, and my ex-girlfriend had a V-6 as well).
