We are exacting, just like the German manufacturer brands that we service. This 2001 Porsche Boxster 986 exhibited symptoms of needing a new clutch. Once the transmission, pressure plate & clutch disc were removed, we measured the rotation, rock play, and teeth count spec on the dual mass flywheel to provide an accurate recommendation for replacement. Visually looking at the surface and rotating it back and forth by hand are superficial and may be the only way other shops may or may not recommend a new flywheel. We opted to invest in the factory tool to verify these specifications to ensure our clients save money by NOT having to redo this work based on a visual inspection and “it seems okay to not replace.”
