Sounds more like hesitation or a misfire.

MY CAR HAS shudder too when I start the engine cold. this shudder is happen often when the engine is cold.
Is it normal?

The hesitation will gone once the engine is warm up.

hesitation is normal when cold, but when the clutch & engine warm up it shouldnt be a problem anymore, unless you are just at too high of a gear for the speed you are going. if the hesitation doesnt go away when warmed up, then it may be a problem. have it checked out by a dealership and hope they're competent enough to find the problem.

Boneamania - My dealership is replacing my clutch on Monday because I have cold chatter. I told the service rep to look up technical sernice bulletin 03-51-02. He got on the phone right away, and ordered my new clutch, another WRX in Sarnia has been through 3 transmissions because of CCC. I hope mine is fixed before it does any damage to the tranny.

This is wrong. Only a Subaru dealer can perform work under warranty. You may be thinking of routine preventive maintenance, which can be done anywhere.

This may be the car transitioning between open-loop and closed-loop boost. This is set to occur at 50% Throttle Position, stock. I still get it occasionally. It feels like the engine is stumbling, and the whole car shudders a bit. I get mine the worst after a reset, and then it flattens out, but occasionally it comes back to haunt me. Usually in 3rd gear, and normally when the car is not quite warmed up.
