i just replaced my mount. I have an 02 with 33k miles. the stock mount was torn in every place that it could be torn. I haven't had a chance to drive the car yet, but the stock 987 mount feels really soft. I hope it takes away the 3000 rpm vibes. by the way, the replacement procedure is pretty easy, however, I have a 4 post lift in my garage, so that makes lots of procedures alot easier....
