RE: d-box
i ran the a-type tires that came stock with the rs4 drift until they literally wore a whole in the rubber. so i figured i was good enough for the t-type tires. i took me a good 10 hours combined to control it. its that much more slick. it is really like driving on ice. if your stopped and give it full throttle real quick you will sit and spin for a second. i like it cause you can't go past half throttle before you spin out so it keeps you in the low rpm's. a-type is definitely the beginner tire and is good. but if you want to compete or show your friends how good you are. get some t-type and it gets real technical and looks way more sick! you can slide slow at big angles.
something i used to help me learn was get a friend or someone to set up a course with cones and practice it over and over till you get it down then run it backwards. keep having them change the course then you get a feel for how much steering/throttle gets you what angle and exit speed for the next corner. if you aren't trying to compete at any point, by all means take it out and have fun. but i have found this a very successful way to go.
