Upgrade your BMW's performance with the SPEC Aluminum Flywheel, designed for models 135i, 335i, 335is, 535i, and Z4 from 2009 to 2013. This high-quality flywheel enhances your driving experience with: - Lightweight construction for faster acceleration - Improved throttle response for a more dynamic drive - Durable aluminum build for long-lasting performance - Precision engineering for seamless fit and function - Reduced rotational mass for increased engine efficiency Transform your ride with this essential upgrade and feel the difference in every drive.

SPEC offers thousands of applications, including a wide variety of performance stages, multi-disc assemblies, tuned billet flywheels, lightweight options and more. All designed, hand-built and tested in the U.S.A.

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.

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.

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.
