My first time running in Yellow group. Ran a 1:42.2 which beat my previous PB (last visit to RA) by over 4 seconds. Was on Michelin Sport Cup 2 tires, 315/30/20 square. Thanks to my good buddy in the Ginetta in front of me – he sensed I was on PB pace and dove to the inside in Turn 7 to give me the line and save me some time and speed down the back straight. #jzilla #jzillatrackdays #preheatthepetit #shelbygt500 #gt500 #shelby
