Way to be dicks, fellas.
If you want to get the car sideways for fun once in a while, you probably want to avoid the hacks and modifications presented here to convert to RWD in favor of finding a dirt lot somewhere. Give the lot a once-over, looking for larger rocks, construction debris, holes, tree stumps, etc., then start getting a feel for how the weight transfers when the tires break loose. Somewhere around 3000rpm in second gear, (Scandinavian) Flick the steering wheel one way, then back the other, getting on the gas as you do. You should have enough boost on tap at that point to take advantage of the rear wheels coming loose. If your driveline is mostly stock, keep in mind that breaking tracking on one wheel will result in all your power going to that wheel (open diffs), so you want to GET ALL FOUR WHEELS LOOSE.
The thing to remember is, drift cars are a spectators carnie ride. They are not race cars, but caricatures. They are designed for one purpose - to burn through tires and sell product. If RWD is so ideal for drifting, why do they all have to butcher their suspension and steering geometries to do it? I say BOO. Dirt is for racing, tarmac is for getting there. The "style points" awarded in dorifto events, with their flat brims, puffy shoes, black socks, and stadiums will never hold a candle to stringing dozens of balls-to-the-wall, four-wheel drifts together on gravel out in the wild, with crests and jumps and exposures.
You haven't lived until you've used your right foot to keep an AWD car sideways for like a solid minute on dirt. (TIP: Dry lake beds are ideal, just watch out for nails.)
YMMV
