Thanks guys.
I was happy the car did as well as it did. She's down on power, but damn can she dance!
The STU 350Z made the run in 10:13 back in 2015. The street-class FRS took 10:18 with the Focus RS in the way for a bit, but I still don't think a fully open run would have covered the whole gap. I was holding more speed through turns and transitions but not quite enough to fully cover the straight-line advantage the STU Z had.
