I suspect an SS is calibrated differently from a 1LE?
I have not had even a hint of it in 2 yrs of tracking mine at several different venues. And i dont believe any other 1LE owner reported this issue regardless of tires and pads...I did experience it once in my old C5Z at the Glen. I was on slicks, with aggressive pads and aftermarket suspension. Here is a link to some info on the subject from a Vette Forum. It does appear to be ABS calibration related and perhaps influenced by mods:
