So my brother needs to replace the clutch on his 03 cobra. Can he resurface the stock flywheel and use it with the new clutch or does he need to buy a new flywheel to replace the stock one once he replaces the stock clutch. Im not sure if its true but we've heard the stock flywheel on the 03 cobras is aluminum with steel inserts. He was thinking of going with a spec stage 3 clutch, an act clutch or a centerforce dual friction clutch. And for those guys who have any of these clutches in your cars can you tell what you think about them. Any helpfull information from you guys will be very appreciated.
