I've been experiencing engine vibration lately. I am going to replace the clutch and flywheel since the clutch is due for replacement anyway. My question is, does a manual 4.6 3v benefit from something like an ATI superdamper? I have a friend with a suoercharged auto who has one but I don't know if n/a manuals benefit from it. Since we're already in the topic of the clutch. Which is a good choice for a 2007 GT with 300 hp and 310tq to the wheels, that serves as a daily driver and track day car as well as some drag racing with street tires? Spec is not an option.
