i have a micro rs4, and i can drift great! well the car can drift great, i need to learn some more, lol. i have a tuned 370 motor btw, but you can drift with the stock one. i made a set of pcv tires, and they work great. if you use electrical tape you cant use it for long if you are drifting on pavement. here is a vid i made of me drifting my mrs4:
