Here is a 2:17.xx lap driven with SimCar (https://matei.one/idxscr.html) car #4 on ZCT289, the current ZakStunts track. It was driven OWOOT almost to the end (I made a concession at the final pair of ramps).

The rocket feature is an interesting addition. Besides being useful for Stunts tracks (as the readme suggests), it fits the setting pretty well. (The mechanics may be very different, but jump boosts in Stunts 1.1 are a form of boost that's crucial to the gameplay. One might even draw parallels to the special modes of the Speedgate and the KITT.) Oh, and the loops feel nice to go around!
You drive quite well, but I don't know how you drove through the corkscrew at 1:55 like that, i.e. like people usually do in Stunts. I only do it like this (0:57, 3.03, 4:51):

That is impossible with some tracks and with physics, unless I also put a rocket for braking. I would just jump normally over the ramps and return from the grass, or the water. As can be noticed, the water is not deep and the car doesn't sink in it as it also shouldn't in Stunts, where the ships can also be put on land and they look the same. Some tracks also have buildings on water and people must be able to get to them, obviously.
