Centerforce
Centerforce offers a multilevel product line, allowing customers to choose a performance clutch that matches their application and driving style. They are designed as an improved OE-style, direct bolt-in replacement performance clutch, and the unique Centerforce pressure-plate design allows for easy pedal effort and everyday driveability while offering increased holding-capacity for maximum performance.
Centerforce is probably most known for its dual-friction clutch assemblies, which have a full facing on the pressure-plate side for driveability and longevity, and a carbon-composite segmented facing on the flywheel side for a positive engagement and increased holding-capacity. Before you need that type of clutch holding, the company offers its Stage I and II systems. While beyond the dual-friction, it offers the DFX and LMC or light metal clutches.
The DFX line is aimed at high-end applications that continually demand increased integrity and holding-capacity, such as high-horsepower Terminator Cobras. Centerforce claims it does this while providing some of the best driveability and easy pedal effort from a race-inspired clutch. The DFX performance clutch system is SFI-approved for competition, with nodular-iron pressure-plate rings and reinforcements designed to help prevent drive strap breakage and safety.
Centerforce's new LMC (Light Metal Clutch) series is a low-inertia performance clutch designed to reduce engine rotating mass. These lightweight SFI-approved clutches were made with most road-racing and circle-track applications in mind, which is why we installed one in our own corner-carving project, Stolen Goods. Centerforce machines the LMC pressure plates from high-strength aircraft-grade billet aluminum and then attaches special heat-treated replaceable friction surfaces. A dual-segmented carbon-composite friction disc is utilized, and the pressure-plate assemblies use Centerforce's patented centrifugal weight system for maximum grip while maintaining a comfortable and controllable clutch pedal.
Centerforce also offers SFI-approved performance flywheels in both billet steel and aluminum, as well as its 400-Series flywheels, which are O.E. cast-iron replacement flywheels and not SFI-approved for competition use.
Fidanza
Fidanza is most known for its performance flywheels, but the company has recently hit the clutch market full force. Its most recent additions to the clutch family are a line of twin-disc clutch applications for the '86-'95 302 5.0; the '96-'04 4.6 GT, Mach I, Bullitt, and Cobra; and the '05-'07 4.6 Mustang GT.
These twin-disc clutch kits include the pressure plate, floater plate, and twin discs, as well as a lightweight performance flywheel. Fidanza Stage 1 assemblies are rated at 650 lb-ft of torque and Stage 2 at a stump-pulling 825 lb-ft. Fidanza claims the twin-disc clutches are engineered to tackle up to 800 hp with virtually no change in pedal pressure. Smaller 8 3/4-inch-diameter discs are used to control the rotating mass of the clutches while maintaining a sizeable surface area for optimum gripping power. Fidanza straps the floater plate on all of its clutches to eliminate the annoying rattle for which twin-disc units are known.
Fidanza also offers a performance clutch kit for the '05-'07 Mustang GT 4.6 in four different levels of performance. Each clutch kit includes a pressure plate, clutch disc, throw-out bearing, and pilot tool.
In addition to its twin-disc clutch systems, Fidanza also produces high-quality aluminum flywheels, clutches, cam gears, flex plates, CV shafts, and short-throw shifters for track, tuner, and street applications.
