everybody is using sports, i hate that, with sport you don't get a smooth drift...
I use different tires depending on the car/power level. I can get very smooth drifts in 400+hp cars on sport tires. I've got R1/R3s on some of my cars. It just depends on what works best for a given car/setup. I usually try a few different types before I get the results I want. N tires are usually best for anything below 400 hp, I find.
