Best thing to do folks is to show up and when you tech in they will get you figured out, don't worry about classing, especially if your a noob. Do sign up for the Novice Trophy if your a noob though, if they still have it?? Kale?
No. See Car and Driver mag from Feb when they did their "Lightning Lap" at VIR. Boss 302 Laguna Seca was 4 sec a lap slower than a Grand Sport Vette. Now on a 4 mile circuit that's a small gap but still. Vette is the stronger performer period. Will just come down to that or if you just have some personal preference.
