I asked over on TMO Facebook about the difference between a Boss flywheel and a GT flywheel and got, as usual, excellent answers. Now I will ask here about brands. Originally I was thinking of an Exedy Mach 600. Now that it appears I need a flywheel as well, has anyone had any experience with the Mantic single disc clutch? I am staying N/A for the foreseeable future as I am not finished with doing track days any time soon. I don't feel the need for a trick multi disc clutch.
