Slicks are worth a lot more than the 1 second he needs lol ill bet Treynor beats that time with fresh oe rubber and more seat timeIts fricken amazing that randy was able to do that in a manual car (Viper ACR). You prob know Darius Khashabi (another bay area dude). He was there the day after and saw a dumpster full of kumho tires. LOL they dialed that car in and used a ton of kumhos.
Are the wheels on the senna light? I think you can eclipse that time with the senna, slicks should get you there.
