That's a great interpretation of the pic, let's go with that! This was a shot from my first run (instructor riding shotgun). I had never driven the track before (studied it on trackpedia.com, great site for those who want a breakdown of different tracks). The instructor was very impressed with the braking power... after a few hard brakes, he admitted that I could go deeper into the turn later in the day (I wonder if he meant with him out of the car lol).
Chris - do you remember which corner you took that shot from? There is a spot on the track where you brake from 100+ down to 50mph or so, but I'm not sure which corner this is in the shot.
I have owned a few Vipers in my day (along with 911tt, Gallardo, 360, etc.), and I must say that I am VERY impressed with the stock Gen III brakes. Never once did I feel as though braking power was lacking. Handling was mostly neutral, although I was running stock runflats and stock alignment so understeer was a slight issue (as evidenced by one off-track excursion). Next stop, the alignment shop! Might look for some cheap track wheels and tires as well.
P.S. - Car is stock with the exception of Motul 600 brake fluid
