Nice, PS4 are the way to go.
Three thoughts re: traction control.
1) how long have you had the tires 2) what climate are you in and 3) did you get you car re-aligned?
I consider 500 miles to be the break-in for new tires. Could be that they're just not fully concentric yet. Second, Michelin recommends them to be used in temperatures over 45*F for optimal performance. Third, if they aren't sitting properly, obviously this would affect traction.
And when you say judder, what do you mean? Traction control in these cars is pretty good, nearly any slip can set it off. I have the AWD 2.8i so spinning tires at a start isn't a concern for me
but a shake when taking off usually would indicate a problem, assuming you're on a decent road surface.
