Wow, 15mph looks fast from that video.

Wow, 15mph looks fast from that video. And you are chin pressing a camera and holding a phone. Are you sure you are not a stuntman? Looks really smooth though.

Then don't raise the front, the CG is too high already. Lower the rear. Whatever that takes. Then find a really flat floor, and make sure that with about 6psi in the rear, and about 10 to 15 in the front that the load on each front caster is the same.
And make sure they run true. To a mm. And you may not think it matters but balance the caster wheels/tyres.
