As I stated, it will go into gear just doesn't feel smoothly kind feel like a bump in between or something blocking in the middle, and yes I always press clutch to the bottom. I think I heard some of my friends experiencing similar issue with their STis.
I'm just wondering is this a common thing? Is it because of my driving habit or shift timing?
It could be how you're shifting or your synchros could be a little worn. It would be nice if everyone could try an unsynchronized transmission, it tells a lot about ones shifting. With a unsychronized tranny you will grind if you shift too slow, too fast or you let off the throttle wrong.
You could be upshifting too slow or too fast, meaning your synchros have to do more work, hence the bump. When you downshift try rev matching.
