Ok some myth busting here, the lighter vehicle does not always not always win. Skill and the ability to maintain momentum, the ones who find the line quickly will always be fast.
Yes NatC is lighter and thinks faster then us guys (most women are that way) but Rooster has a lot of auto-X experience (the programing will kick in). Redhead also has track experience, Audio is also lighter then us guys and me yes I have been to K1 before but the Anaheim track has changed configuration a few times. and I promise "I wont do any training"
A few things you need to know about K1.
1) its a asphalt track and the tires are soft compound = Grip. If you go too far off line you will loose grip in the marbles. Also you need upper body strength I don't know of anyone yet that's tried it for the first time and didn't come away with sore forearms, shoulders and pecs.2) Electric karts have tremendous torque = max torque a almost 0 RPM.
3)You have to wear a helmet with the visor closed.
4) the Anaheim track turns down the lights so its like night racing (the main reason I like going there).
5) You race the clock but you still can be flagged to let some one pass if you are slow.
6) They can hit up to 45
