I'm wondering how you know when you need a new clutch? This car is my first manual so I'm not very knowledgeable this stuff. I know when it starts slipping it's a pretty good sign it's time for a new clutch but I'm not even sure what a slipping clutch feels/acts like. How many miles do most people get on these clutches? I've got about 22,000 on my car so far. Thanks guys!
