So i tighten pressure plate down all the way the the throwout bearing can be pushed through the pressure plate by hand... I tried with my old oem and the new oem. What's the problem?!

 

Take pictures of the pressure plate and the throw out bearing in place. I can almost guarantee there is not a problem. What you perceive as centered is not perfect as the guide on the transmission provides. I've installed an ACT pressure plate twice in my car. The throw out bearing is going to wiggle around until you install the transmission.

 

The TO bearing never gets pushed in towards the PP. The release fork (once inserted) will prevent the TO bearing from going in towards the PP. There is no problem from what I'm hearing.
