Any 4wd will do for drifting nitro or electric, although electric is the preferred choice. With the Stage D kit you get an amazing set up for drifting which costs about 10x what a 10ft tube of PVC would cost and you'd have close to the same end result. If you're serious about it, go with the upgrade but it's not at all necessary to have a great drifter, heck, my drifter is my cheapest setup! Not to mention nothing breaks on it outside of normal wear and tear.
