( My first thoughts are weight distribution and its effects on handling.
How will you tackle this problem ? )

This is going to be a really interesting project !

The angles could also not be as bad as they look in the picture. Maybe you can try taking a picture from further back so we can judge the angles.

Sven, I believe he's using the CRX drive, with the motorcycle frame/swingarm modified for a static rear wheel.

HydroJim, it has to do with center of gravity, how low it is and where it is between the three wheels. In a 2F1R (two front, one rear) format, you typically want it between the front wheels, about 1/3-1/4th the way rearward. The TRex type trikes have barely any weight above the rear wheel, hence their ease of sliding out the back end but rarely tipping over.

I'm following this project closely, I've considered something along these same lines but with a Metro XFI.

Though I would wonder about the possibility of doing a somersault if you braked too hard.

this is were the car sits right now will get a fuel tank and battery and seats and people wheelbase is a longer now so tipping is hard. not saying cant happen just need to drive for that info hyper

driving no brakes

This might give you some food for thought when it comes to shaping in the rear gap...

350 no driver no doors and will drive and see how it go. And thanks for the foam vid Will try that when the time comes This may help

Your build already looks cleaner than that.
