nk4e, i have some advice for you.
first off, 4wd drifting has minimal countersteer in-drift...so youre probably not used to countersteering too much.
also your angles are higher in a 4wd, and you can always rely on ur front wheels to pull u through. here are some basic things you must learn to drift FR;
-the car can only achieve certain angle before it spins out...you must learn to "feel" how much the FR car can get sideways without spinning out. remember you dont have any front wheel power to save you. once u start to lose it, you lose it.
-countersteering skills. you will have to learn to apply countersteer early and hold it correctly through the corner. my general rule of thumb for FR is more countersteer is safer then less. retaining grip early can be fixed with practise, but not countersteering enough will cause spinouts and frustration wich will take longer to conquer.
-start off with a stock car on sims, apply basic drift techniques (sway, feint...) and see how the car responds, try letting it slide out and countersteering late just to see if you can recover, this is how you will learn your countersteering timing.
-practise "tracing", the more your rear end comes out, the more you countersteer.
-its better to start off with short small drifts than to try and produce big angle drifts off the bat. starting with smaller drifts will allow you attempt making them longer and experimenting with throttle and steering.
it might take a while, but dont get frustrated...i hope my tips help.
