Not sure what tires the guy with the Z had but I'm guessing he could have stood to run a more aggressive tire. I doubt he could have run a slick (as per USCC rules) but based on his low skidpad and road course times...I'm willing to wager his 1/4 mile time was partially due to a combination of tires and skill. But hey he's faster than me and got in the USCC so props to him.
