I'm not sure of the length difference between a Coupe and a GC, but I have had my Quickjack (BL-5000EXT) since before the M6. I have never had issues lifting any of my cars with it. My previous car project car, an E39 M5 that was LS twin turbo swapped, sat lower than my M6. No issues. I currently have the M6 sitting on it (since November) while building my intake and getting new tires installed on the wheels. I wouldn't worry about it, GREAT tool for my situation.
