Hi the Sakura d3 cs requires a lot of money spent on it to upgrade it to make it even a good starting chassis to drift. It isn't a very easy chassis to set up even when you know what you are doing and with the high cs ratio with be very unstable and hard to control for a complete novice. You would be much better to go for the tamiya ta06 pro chassis or the ta05 pro drift chassis, these chassis's are very well balanced, much easier to control and easier to work on and set up even straight out of the box, but if you did want to upgrade.. Many parts are available.. The biggest thing to remember with drifting is not to over power the chassis with a fast motor as it is all about being slower and more controlled. Also go brushless sensored so it is a nice smooth speed and don't go much lower than a 17.5t motor. A motor that is too fast with have a more sensitive throttle and a narrower top end curve and will make your loose control easily, you will find yourself constantly have to adjust your steering and throttle excessively and never achieve a constant steady drift.
