ET and MPH will also be affected by how you stage the car...deeper = slower ET slower speed...shallow = faster ET and speed.[shallow = givesa rolling 'head start' before the clock starts]

[/ QUOTE ] Huh? what do you mean a rolling start?

[/ QUOTE ] as you stage in shallow your front wheels roll forward a foot before it trips the photocell and activates the timers. so you are actually getting a "rolling start"
