I can drift. Just not on purpose!

From what I hear Assetto Corsa is totally awesome for drifters. Hopefully word will spread among console players and it'll become the new standard for the drifting crowd!
Is that a stock M3 or do you think they tweaked the car? I've never seen my E30's front wheels do that in any replays. That looks like the type of problem that would have been reported and fixed a long, long time ago.
If AC is good for drifting, even stock RX7 will be decent for drifting ( not like D1 pro though ) like it does IRL. I saw the M3 drift vid on the last page,

someone messed with the steering angle, likely a mod

The wheels looks as if it went inside on full lock

, on real car that would be funny if possible. It makes the car drift unnaturally though, the way it change direction ( transition ).
Here is a tip for doing a drift : clutch, play with it, when losing momentum, clutch kick, the handbrake also your best buddy when learning

, use the alignment ( caster at highest possible, front camber, adjust toe, run lower rear camber than front, some rear toe in may help, or just run zero toe or slight toe out if you have quick hands ) Lower steering ratio if you need quicker counter steering.
There was a saying : All RWD can be drifted, there's always a way as long as the rear spins. Dori Dori can drift stock R34 GTR around touge
I already knew I can't drift but if there's one thing this video proves, it's that I can't drift. 
It'll be fun to watch if nothing else.
What tires did you fit on the car ? The real car came with BFGoodrich G-Force slicks, does AC allows road car fitment on cup car ?
The MX5 Cup has more than 155HP ( road car rating ), it has been equipped with race header+full exhaust+tuned ECU (sealed), it should be able to drift ( even with rear torsen LSD ) Front swaybar is adjustable on the real cup car, lower it if it's too stiff to make the rear looser ( about 25-50% more than rear )
Can you adjust the rear LSD or alignment ? Increase caster, zero rear toe, about -1.0 rear camber, higher front camber with some toe out. Lower steering ratio if possible. Increase the rear LSD lock rate, the rear torsen of the real car have low lock %, increase preload as well if possible. Lastly, lower front spring rate if possible.
A good starting car for drifting is a well balanced track day car ( in general ).
