Hi all: Many moons ago (2003 ish), I drove a Dino with a very, very light flywheel (a Tilton 5 inch carbon fiber model). It was beyond amazing, except of course it was difficult to launch. I ended up buying that same car more than a decade later, but the owner had put a standard flywheel back in the car for drivability. There certainly are flywheels in between stock and too lite. I have a lightweight flywheel (steel not aluminum) on my 66 eType and it transformed the car with no downside. Any thoughts would be greatly appreciated.
