Well assuming u already know how to drift...just lower it and get some good parts for the rear end. Then get some power adders to give your stang some more balls. And save up some money for tires. Lol.
LSD, chassis stiffening, adjustable suspension parts, increased steering angle, stiff, not-too-sticky tires but something you can still control...and as many sets as you can afford if youre getting into it.
