rig camera on rollercoaster

[Ram Shani]

hi

i am about to shoot commercial on roller-coaster (it doesn't have 360) and she is going 40KH

i want to shoot 2 persons every time

thinking about alexa mini or sony f55 (global shutter)

and to rig it with SACHTLER MAXIMA but afraid it wont work.....

my plan B is a poor man stabilizer and to put the camera on car tire

any advice will be great

thanks
