I made a clutch install thread a while back, there is a pic of my act flywheel somewhere, I think my flywheel was 4.239 kg in comparasion stock is almost double at 7.803 kg. the moi "moment of inertia" is even less again because all the weight was removed off the peripheral edge with giant holes near the edge of the flywheel. This calculation is probably more important than the total mass because it's the moi that really gives you the rev happy feeling.
I found a clutch install easier and more straight forward than a timming belt change.... Maybe you could give it a go??
I don't have tools nor the space to perform such a task so must spend money on the installation.
I'm choosing exedy hd bc it will last longer than oem and I'm sure IF I sell my car having a exedy HD clutch will be a better sales pitch than oem
