Impossible to achieve high 1.20s sixties

[69Cobra]

I like to stop with the tires at the edge of the water then stab the clutch before the tires grab and put excessive heat in the clutch. So I would recommend that as well as staging as shallow as possible. The other two biggest factors I see is that the wheelie bars appear to be slapping the ground at launch and unloading the rear-end and causing the tires to spin a lot more than I would want. The other thing is that the rear suspension doesn't appear to be separating and planting the tire. So I would try to keep the heat out of the clutch during the burnout, stage as shallow as possible with some break pressure to hold the car still, raise the wheelie bars so they aren't unloading the rear suspension and if that doesn't get you there see what you can do about getting the rear suspension to separate to help plant the tire then look at taking some clutch out of it if that doesn't get you there. Last but not least put a set of new M/T tires on it. Just my .02
