i know this might sound stupid but should clutch fluid be changed as in a one of service ? i have noticed that unless i am taking care with gear change at low speeds or when just cruising its a bit jerky when put gas back on,the clutch is fine and isnt a big problem its just when driving other normal cars ie pug 306 it doesnt matter how quick i let go of clutch its still smooth with the change,with my 02 sti i have to time it well to get the same smooth change,when i give it some and come off clutch quick its ok but at slower speeds and in traffic its harder to be smooth,hope this makes sense to you all wanted to know if fluid would maybe need changing and bleeding

 

clutch judder is a common thing apparently sorted out by a couple of launches.

 

As said, clutch judder is not unknown on Imprezas. Both Imprezas I've had have displayed it on occasions. My 03 STi will often judder the next morning after a long drive the day before, but tends to smooth out as it gets warm.
A fluid change is a good idea as there could possibly (but unusual) be air in the system. Keep meaning to do mine!
