    This is to show the flex in the rear suspension.

    on 2 step:


    Clutch drop/launch:


    This kills your 60' time and the opportunity for the holeshot.

    I launch at 6500 on 24.5" m&h slicks. Tire pressure at 10psi. Full weight, cut 1.71 60'.

    I bogged on a pass last year and broke my diff. This year I'll try launching at the same rpm but I'll be making ~150 more whp.

    I do 3rd gear burnouts but this year I have a longer trans setup. So I'll try 2nd on my first few to see how it reacts. Pull past the waterbox as everyone has stated and burnout. I never pass the lights. I rather have more room to release the clutch early and not red-light. Plus I've seen a few videos of people leaving it in reverse and launching backwards. Total fail.

    Great point on the rear suspension flexing and those pics make it easy to see not just read. Know i know why you said you need 20k rear springs

    I agree with all of this! Slicks are the shit.
