Not on those ones.... That's a wood track, group 27 motor class from what I can see..... Only thing holding them down is the bodies with the wings on them.
This is a group 27 1:24 car like they're racing, basically a wire frame with a big motor and tires...
When you see them in slow motion the wings flatten down and put downforce on the cars.... Then you need to figure out gearing, make sure you put some sticky glue on the rear tires and some braid juice on the front braids that pick up the electric signal....
The hardest part is making sure where you are on the track to make sure youre not on the outside of people in turns, they can goose the throttle more to get the ass end of their car to swing out even more and knock you off track.
