I've been driving my WRB 02 WRX Wagon for three months now.
Previous owner said that it has Exedy Stage 1..
The problem i'm having is that the engaging point is way in the end.
It is right before you fully let go the clutch pedal.

It's not slipping or anything and it has been catching fine.
I learned how to drive manual with this (poor thing suffered :( )
I also rev match all the time.

My friend who helped me installing few parts (down & uppipe) told me that the engaging point is completely different than when he first drove it couple months ago.

Is this a sign that i need to get ready to get a new disc for my clutch soon?

I'm planning to drive to Las Vegas, Grand Canyon, and other places during the Thanksgiving break with my car carrying 3 passengers.. so it's important my clutch won't give up on me during the trip
