Drag Tune Helper
Build or fix a drag tune
Start from a launch baseline by drivetrain, or pick a strip symptom. Retest at the same strip after each change. Launch usually decides the run. Look for controlled rear slip and squat: not full smoke and not a dead hook.

What do you need help with?
Covers tires, gearing, differential, springs, damping, ride height, anti-roll bars, and brakes. Dial in controlled launch slip and squat before chasing trap speed. Gearing: start final drive at top speed, 1st toward accel, shorten FD per pull until launch spins, then space gears on the power band.
