Hey guys plz excuse my lack of clutch knowledge.. After owning several mustangs this has been the first time I've had to replace my clutch. ( had a 04 supercharged Roush, it had 60k miles with the stock clutch when I sold it) I have a 2007 Shelby just turned 27,000 miles and the clutch is starting to slip. It's stock right up to the air filter and I'm not planning on adding any mods any time soon. I'm just looking for a good replacement. I've done some research, I'm confused on weather I need a new fly wheel.
