R comps typically have too stiff of sidewall to get a good launch. You really want a drag radial. Soft sidewall and designed for low tire presure.
I was not joking when I said I don't care about 0-60 times. If you do you better find a way to get a manual car because the SMG launch program wll probably be nerfed again here in the US.
1/4 mile trap speed tells you a lot more about hp/lbs than 0-60
1/4 mile ET tells you a lot more about how well the car launches and how good the driver was.
Skidpad gives a decent idea of grip
Lap times and slalom are so skill dependant I would want to know the resume of the driver at the wheel.
0-60 is a lot like the 70-0mph brake distances the magazines talk about. It doesn't mean a thing. It espically doesn't tell you anything about the cars brakes.
Yes I am a track guy but I am also an engineer. I know a junk stat when I see one.
