Stock 2017 GT350R other than front camber plate (-3.5), GT350 aluminum wheels (narrower than GT350R's CF wheels, I am too cheap to track $$$$$ CF wheels) and 305/325 Goodyear 3R tires (standard on Camaro ZL1 1LE, and lot cheaper than SC2 that came standard on the R). lap time of 1:27.50. This was my first track session ever in this car. This was during time trial of American Muscle Cup Racing Series 12/16/17 first session of the day.

I really was bouncing up and down through T8, this track is poorly maintained and it shows.
This was my first time tracking a GT350R. Weather was perfect. Car was super easy to drive. Though my line (aka chicken line) through T9 was bad, costing me at least 1/2 second.
