We frequently get people using the website wrong and often get questions posted up on testimonials. What you wrote sounded basically like you were telling us your situation and asking us what we would like to do. As for the broken disc. If you look closely at it is is a OEM LUK disc. The same products your installer only uses. We have sold probably close to a 1000 of this design and some have broke. Most go for many of miles. We have since built a stronger design to eliminate any breakage. But the same goes for the factory setup with the DMF. Some people can get 200,000 miles and others have flywheel failures in 30,000. There is always a reason when parts break.
