[V8] UFO brakes

I have considered the belly pan factor too because mine was not attached for at least 3 years.  This covers the time when I was commuting 30 miles each way between 8500 and 6000 feet in elevation.

My belly pan is not back on so with the cooling ducts present, the italian tune-up will hopefully be more effective.

... it might also be interesting to keep track on "warpage" based on AT vs.
MT (I used to think that the UFO problem was correlated to this, but all
200Q20Vs have MTs and we see reports of problems from folks with MT-equipped
cars) and whether or not the belly pan is installed.  The belly pan includes
the brake cooling ducts.  My data point is somewhat inconclusive ... I have
2 MT cars, for the most part one has the pan installed and the other does
not (although there have been time when both did and others when neither
did).  As reported earlier I've never had an issue with brake pulsation on
either car ...
