The automotive component most responsible for insuring optimum clutch performance and life is the flywheel. The flywheel;s contribution to power transfer is three-fold.

Firstly, the flywheel should provide a consistent and friction enhancing surface for the clutch disc. Flywheels also aid in proper inertia, which is determined by the flywheel weight. Inertia controls the ratio of power to acceleration and can make a vehicle faster or slower based on gear ratio, tire type, vehicle weight, power output and even the location in the powerband output is achieved. The weight of a flywheel and amount of inertia it provides can also effect drivability. Lastly, the flywheel must provide a true balance at rpm, which means no dimensional runout that produces engine damaging and power robbing vibrations and allows smooth engine revolutions.

SPEC flywheels are CNC manufactured at an unheard-of .001 tolerance, in an industry where the standard is .010. This precision manufacturing process ensures perfect balance and a perfectly flat bedding surface for the clutch disc, both of which also contribute to the ultimate in safety for competitive environments. All SPEC flywheels carry SFI certification. (sfi link)

To allow for specific inertia needs, SPEC flywheels are made in high carbon billet steel and aircraft quality billet aluminum. The aluminum and most steel SPEC units are rebuildable and feature a replaceable steel friction plate that is made from a friction- enhancing steel metal specially formulated for optimum clutch bedding and holding power. The aluminum and steel materials provide a light and medium weight option for all types of racing. SPEC spends a lot of time and effort on research and development of optimum flywheel dimensions and weights for all types of driving and racing and can optimize your MOI (moment of inertia) to maximize your car;s output and performance.

Who is SPEC Clutch?

Back in the day, engines were only rated at less than 50hp. Having a 100hp vehicle back then is considered as a performance race engine in today's standard. But as technology evolves so is the horspower.

Today, you see engines having more than 1000hp, some even reaching five times that number. And with that much output, there is a need for a drivetrain component that would be able to handle this much power. SPEC Clutch is a company that can deliver just that.

Based in Bessemer, Alabama, SPEC Clutch was founded by automotive enthusiasts and racers who were motivated to build a better product than what was available to them. SPEC Clutch assembled a team of experienced engineers, clutch builders, machinists, and other petrolheads to build the brand, which began producing clutches all day in a 5,000 square foot building. Using their expertise, they were able to create a clutch system that is not only easy to use on the street but also can perform on the track. 

Their clutches are considered some of the best ones available in the market and has exceeded the expectation of many enthusiasts everywhere. Due to the increasing demand for their products, the company has expanded its operation and now resides in a purpose-built 30,000 square-foot state-of-the-art facility, where they design, test, and manufacture all of their products in-house. It allows them to maintain their high level standard and enables them to control the manufacturing of their parts. This means that all clutches, flywheels, and pressure plates are designed under the same roof and optimized to work together to deliver the best results possible.

Sheer Dedication to the Industry

SPEC Clutch has since become an industry-leading company renowned for its high-performance clutches and flywheels available for nearly every vehicle and application out there. SPEC uses only the most advanced fabrication processes under the strictest tolerances. It offers thousands of applications, seven stages of performance kits, and up to eight stages of multidisc, stock appearing, and billet lightweight clutches. This company provides the only flywheels on the market manufactured to a .001 machine tolerance to provide ideal rotational integrity in even the toughest of conditions. 

SPEC Clutch has become a mainstay in a variety of motorsports and employs a certain number of racers at hand to ensure its products work. SPEC Clutch also takes the time to engage in a number of different racing programs in order to continue researching and developing its components and systems in real-life competitions. After all, the ultimate test is seeing if the product does its job out there in the real world.
