Those are all pretty good cars. Every touring car is capable of drifting basically. The TT01 is known to be a great entry level drifter. The Sprint 2, I heard, is good as well. Although I would prefer a TT01 over a Sprint since the TT01 is a kit, and I always liked kits better than RTRs. But that's all based on your preference. The basic thing you need (and most important), is drifting tires. Most commonly, people get PVC/ABS pipe (2'' inner dia.), cut it to width of the rim, and slide it onto the rim. PVC works, but ABS is overall better to use. If you don't want to do that, and want to go a more expensive way, get yourself some Yokomo drift tires. I'm not exactly sure how they perform, but people suggest them. You can also get yourself Tamiya's set of drift tires that come stock in the TT01D kit (TT01D is drift spec, out of the box). So if you're looking for a good drifter, out of the box, I would get the TT01D kit for now. The stock tires don't drift amazingly on rough grippy surfaces, but they perform great on smooth treated surface like garage pavement.

So good luck to you, and if you have any more question - ask away =).
