Good considerations.
I have to say that on dry asphalt I never felt or never experienced traction control action (performing 0-60mph on straight road) . Even with low profile 235/35-20" tires. Traction control (instad on curves) is terrible , it cuts power in a INDECENT way.
my best (easily repetable ) is 3,22 , 3.03 (1ft roll) with 20 Uberturbine rims and crap 235/35 Pirelli PZero.
You can say: " You don't feel it but probably it is acting nerfing power". And I agree.
The fact is that i tried many times also allowing "Slip Start" and I never had better result on 0-60mph.
I have good experience on drag racing (Ice cars) and I'm able to feel the tires slipping.
