All auto-x starts are standing start…and the place you lose most time trying to get traction to shift into 2nd gear…all of auto-xing is based on a good launch and getting to top speed of the car in 2nd and then maintaining that momentum. Launches are when my car is the slowest…2.2-2.5 60 foot isn’t so hot…the spring will stay compressed longer and not allow the control to droop.
