How does cold weather increase traction?
I was wondering how cold weather cold make traction better, because i have noticed cars getting low numbers(Stock) in cold weather like for example stock 2002 Z28 13.3 and if better maybe a flat 13!!!
Thxs in advance.

It's not about the traction. It's about the colder (more dense) air. The cars are making more power thanks to the cooler, more dense air charge. That's why they tend run better times with the same (or even slightly less) traction on a 45 degree day with 30% humidity, rather than what you'd see on a 90 degree day with 95% humidity.

That's the dichotomy of cold weather/great D.A.s. Although you are making max power out of your stock NA motor, your street tires CANNOT hook for $h!t!! Now, well heated Mickey Thompson drag radials (or better) will cure that, but NOTHING is going to help much < 30 degrees F.

This thread is only partially true - extreme cold may suck for traction, but so does extreme heat. A really hot track can get greasy and make it hard to hook up. A more correct statement is that there is an ideal temperature range for good traction.

I guess if it's super humid/damp out, the moisture might effect the ground and hurt traction, but heat alone has never been a problem for grip, in my experiance.

It depends on the track surface - I have seen some tracks that get oily from the sun baking the asphalt. I agree with you that most times hot weather results in better traction, but extreme heat at some tracks can make things slick for certain car / tire setups.
