The clutch engagement point can be adjusted.
Here's the 2004 wrx manual page on doing that. There's a second page right after this one but it only has 2 items:
9) If the clutch fluid level does not increase or push
rod does not retract, clutch pedal must be readjusted.
10) Check the fluid level on the outside of the reservoir
tank. If the level is below “MIN”, add clutch
fluid to bring it up to “MAX”.
Apologies for the shitty quality on teh manual page. TR only allows a maximum height of 768, rather than the native image's height of 785 so I had to resize it and it didn't end up being that good. If you can't read it, let me know.
