2 days after I got mine I took it around Donington race track. The electronics really "trimmed" the attitude of the car in 4-wheel drifts, and I was surprised at how much fun it was. I was expecting it to be a bit restricted.
However, when driving on a spirited manner on the road you cannot go anywhere near the limits you would on a circuit. Therefore 4-wheel drifting is not something you can do on the road. I feel it does take something away on the road, but again, it's good for the average road user in case they get into trouble.
I removed the fuse a couple of months ago to see what it was like. I must say that for me it improved the whole thing - the rear would come round very nicely, in a controllable way. However, I did put the fuse back before my girlfriend drove it! [img]smilies/tongue.gif[/img]
