Yes I have the same issue on wet roads. It only happens from a stop. It is the brakes grabbing as the TC engages. The speed a which the tires are spinning then the brakes trying to stop the spinning causes the violent thud. The wheels do not spin as easily on dry roads so not as violent when TC kicks in.
I'm wondering what will happen in snow. Same effect or not as violent.

It's wheel hop and engine movement. One of the biggest issues from the factory with our cars is the squishy engine mounts that allow a massive amount of engine movement to provide a smoother ride with less vibrations. Upgrading the rear engine mount is one of the easiest and cheapest mods a lot of us has done. It helps with the wheel hop and engine movement, but not drastically. I'm still waiting (nay, hoping) that someone comes out with a full set of engine mount inserts for our cars, like what I have for my '03 SpecV. That helped tremendously with these issues, but does transfer a bit more vibration to the cabin, especially via the shifter (if you have a manual), and the pedals.
Just be forewarned, while it's fairly uncommon, a lot of hard, repetitive beating on the engine mounts can make them fail, and fail hard.

I've still been able to get it to chirp the tires before it catches them at times on wet pavement or going around a corner at low speeds.

|ivofe||One more thing don't know if this makes a difference but i do have sport suspension option on my 2012 TI. Maybe the springs or even the 18 rims? Really has me scratching my head.|

Checked right wheel its not loose. Thanks for all the info looks like a trip to the dealer for me. I have had numerous vehicles with TC and never had that hopping clunking sound when it kicks in. I don't think it is normal.
Thanks again and any additional responses would be appreciated.

I have a similar feeling. TC off is normal, but with TC on and a wet road, if I accelerate and it turns on it chops/pulses really harshly, and everything bounces in the cup holders. In the snow, not at all. I felt similar rattling in the cabin once when I ran through a pothole at night that cracked the sidewall on my tire.
I'm not sure if it's normal, I know it's obnoxious and sounds harmful on a wet surface, and it'd probably scare the crap out of any passengers I have if it activates.
