No claims to knowledge here, but I watched your vids multiple times and something doesn't look right to me...

Then I pulled up this NHRA Stock Eliminator video and watched a bunch of cars making passes: https://www.youtube.com/watch?v=htn-mn4lCOk

The only "conclusion" I can come to is your car seems to be wasting a lot of energy off the hit... you can see it jerk on the hit, then it doesn't move cuz it's just wadding up the tire at first. Then the front end kind of bounces like it's too loose on the compression after it extends... and your front wheel looks like it's just flopping around, too.

What size rims are you running? I think they're too narrow for that size tire.
