Same car as Thunderhill post above. Bone stock. DSC fully on (again, a mistake).

DSC partially off, plus better tires, plus DTC-70 front brake pads, plus toying with a few different racing lines translated to a nearly 8 second improvement per lap.
Apologies for the crappy audio. Experimenting with new external mic and mounting it behind the passenger seat did not work. It would rattle against the plastic seat backing, causing that noise in the video.
