old post followup... MPfab developed the DRS to get more power to the ground + consistent handling, it's a nice piece. More and stiffer mounts feel a little more vibration through the cabin and stress drivetrain components more, but that's not what his part is about.
I've found the weak link in the drivetrain to be axles, I've replaced two. One axle took a wheel bearing with it when it crapped out. The transmission is a weak point but only from hard or hot shifting.
Mine started the motor mount shake again a few days ago :blankface: Dealer replaced one under warranty a few years ago. Will go with upgraded ones soon. Small vibrations from upgraded mounts are better than broken mounts :sadbanana:
