Your not saying that Ford should shave tires, tune the chasis(suspension and splitter/spoiler down-force), tune the motor, take out unnecessary oem weight off, for one specific track in order to achieve the fast lap times? All for what....marketing purposes?
You forgot to mention adding a full roll cage which has a dramatic affect on chassis stiffening and track times. I noticed the "Ring" times are advertised (talked about) by GM and GM faithful on a regular basis without mention of this fact.
I know Ford also tested with a full cage too but you don't see them advertising track results leading people to think those results are from a bone stock factory car like our boy Al is doing.
That is interesting, I did not know this. I was under the impression both Ford and GM tested their cars in stock form. If this is true then it is very misleading.
