It's the "Last Three Designated Pair Rule".
I recommend not being late to the lanes with Nitro Joe in the back.

We will run as efficient a program as is possible, by dividing up the field. (different colored run stickers in Qualifying). When we call you, we need you. Get there, suit up, last checks, get in, and go down the track. That way people don't have to spend an hour lounging in the staging lanes, and can spend more time enjoying the race, working on their cars, benchracing, grilling out, or what have you. Remember that despite having 300+ cars, we'll still have just two classes, so it will feel faster paced than an LODRS.
