I have a bolt ons car with a spec 3. the clutch has seen 25,000 miles. if i'm doing say, 50mph in 5th or 6th gear, i can push the gas in and i get a grinding, shaking throughout the whole car, I'm positive its the clutch. Also i can put the parking brake on and just about let it idle with the car in gear and clutch disengaged... (wont stall)...

The other thing is... when i push the clutch pedal in... i dont think it ever fully disengages... so, whats my problem? it doesnt fully engage (worn clutch?) and it doesnt fully disengage (worn clutch OR air in clutch lines?) what do you think?

and

i need to know if i can get another 200 miles out of it or not.

Thanks!
