Don't want to add to the p____ contest already in progress, but I have $0.02 to add:
1. As others said: You will not "hook" in 50F weather on street tires.
2. Don't do shitty acceleration videos with handheld phones. It's stupid, don't do it. Secure the phone/camera and/or use GPS apps.
3. You don't need an LSD. BMW eLSD is fine for straight launches. Go outside now, do a hard launch. Count number of black marks on pavement...
