Thanks for sharing the vid!
Loved it!
I understand people wanting high performance summer tires for their cars.
But why do people go extreme on the grip?
1. paying for high grip semi-slick tires on a road car
2. go to a track with the tires that the car was originally not made for and put a lot more wear on every component of the car. Making it wear out faster and having to put more money on it.
3. Doing the above and ending up having less fun.
The only people I see doing this with "good" reason are:
1. people that sucks at driving and want to keep up with the faster guys without having the skill or the poweroutput. Thereby having more fun since they are able to be competetive or seem faster than they are.
2. People that have dedicated track-day-cars that have been modified to be up with that fastest in car classes that does not limit the cars to normal road tires.
What is up with all the other people doing it??
I see more smiles on people playing with the limit of grip than people on sticky tires.
I once was a passenger in a E30 325I on a small track. Toyo R888 on the front and crappy tires on the rear. That combo worked too, even tough it was kinda stupid. Was great fun playing and going sideways, without being in the way of the people that were going fast on the same track with normal tires.
BTW, would love the see the face of a salesman if I asked, "Could i get my GT86 with four spare tires fitted"..

Worst thing about all this, now I would really like to try this for myself!
