The pavement crowns a bit where the banking levels off as you exit Turn 13 at Chuckwalla Valley Raceway. If you walked up to it and took a look, you’d probably wonder what the heck I’m talking about. However, if you’re behind the wheel of the new 2016 Lexus GS F, extracting as much acceleration as you dare from the bellowing 467-horsepower 5.0-liter V8 engine, that subtle change in the track surface feels like a sudden and violent shove — a foot into the right side of the GS F’s figurative back attempting to punt the rear end into the dirt.
And you don’t want that to happen.
