You want to bring your late model Stang up to snuff, and so does Quarter Master. The company’s 10.4-inch clutch kit, the Optimum-SR, comes in one- and two- disc variations, operates at a lighter weight for less rotating mass, and best of all, gives you the kind of response and feel you desire when pushing the car to its limits.
Official Release:
Quarter Master has created a revolutionary 10.4″ clutch kit for late model Ford Mustangs, available in both a single- and dual-disc configuration. The Optimum-SR is a true racing clutch with factory driving characteristics to replace the stock component.
Each kit includes engineering know-how derived from the Quarter Master racing heritage. However, the clutches can easily be used for street driving.

Iron and full-race kits are also available.

- Significantly lighter than OE clutch; less rotating mass
- Billet construction with proprietary spring technology
- 100% re-buildable for years of service
