If the OE clutch/pp/flywheel assembly doesn't get the disk on the splines sufficiently, then the face of the bell will be milled in hopes that it will do the job. Of course everything you remove from the bell is going to also reduce its strength. I don't think 10mm would be an issue, hoping it won't take that much. But until I get everything in place I won't know. Still have a turbo to install first.
