First time I was called the Rabbit of our group, I help a Corvette achieve his Personal Best :)

Running my new NT555RII on their 1st Track day. 
Very happy with the tire. Consistent feel lap after lap and they warmed up after the 1st lap pretty well...but I'm a heavy car 4120lbs. 

Finally dipped below the 1:40 mark (Previous Personal best on MPS4S)

Hot Pressures = 39psi seemed to be the best for shoulder roll and grip
1.3G's of Grip!! (per Racebox) 

2012 ZL1 with some mods
Back to Factory Pads and Rotors... Brakes got slightly faded but never fully gave out like my PowerStop Track Day pads and EBC Rotors did. 

Might try Carbotech XP10 pads next with OEM Rotors, if anyone has feedback on those, please leave a comment!
