FIRST YOU HAVE TO SET YOUR CAR UP FOR IT...... to make it simple just go buy simulation tires, stiffen your suspension, and go ahead/// usually around 200-400 hp is good for most cars, you may need less or more.... just drive the car with simulation tires for a while and you will get the hang of it... I USUALLY INSTIGATE THE DRIFT BY POWERING IN TO A CORNER,,,,, getting the slide is easy... holding and maintaining it is what takes skill... OH HERES SOME ADVICE... never pull the handbrake to start a drift... use the wieght of the car to get it to slide... im assuming you know what drifting is and have seeen real life videos..... its all about THROTTLE CONTROL and steering.. heres some advice.... the more throttle the more the car will want to spin (SPIN NOT SLIDE) hence if you add lots of throttle you must combine it with some steering.....
LOTS OF THROTTLE=tight circumfrence drift
LITTLE THROTTLE=long flowing drift drift
JUST KEEP ON PLAYING AND PRACTICING... the main thing is SIMULATION TIRES though.. if you want to make it a bit easier buy full customize LSD(limited slip differential) and raise the intial TORQUE to the max (60)
