I own a GT6. It is a fun car to drive. Light and quick with about 120 HP. These cars weigh less than 2,000 lbs and are very small. You don't sit in it as much as you wear it. You also have to drive it like you are riding a motorcycle; head on a swivel and assuming people don't see you and if they do, are trying to kill you. If you get into an accident it's bad news.
Now add another 200 HP without modern brakes, traction control, air bags, crumple zones, visibility, etc.
I have a friend with a 427 Cobra. When he drives it it takes 100% of his concentration and will break loose at the slightest push of the skinny pedal. When he wants to go on a fun drive he takes his 75 HP Spitfire. Kind of like taking the 650 out rather than the CBR1000RR.
I think you might need to actually watch the videos before commenting, that way you might know what you are talking about.
He's built a new frame with new suspension and brakes made for cars which weighed more than twice the weight of the GT6.
