Spec Clutches and Flyweels Instock No Waiting!!
Spec Clutches
Stage 1
Types of Driving: Street, Drag, Drift, Road Race, Rallye, Pulling, Autocross
For bolt on naturally aspirated and mildly modified forced induction engines. Stock-like daily drivability and very good wear characteristics.
High clamp pressure plate, steel-backed and multi-compound woven organic material and high torque sprung hub and disc assembly, bearing and tool kit.
Spec Stage 1 Clutch Kit Evo 05-07 (PM For Price)
Stage 2
Types of Driving: Street, Drag, Pulling, Autocross
For all mild to moderately modified naturally aspirated and power adder engines. (Also good for stock power levels and spririted driving when good daily drivability and extremely long life are the goal.) Stock-like daily drivability and EXCELLENT wear characteristics.
High clamp pressure plate, pure Kevlar friction material and high torque sprung hub and disc assembly, bearing and tool kit.
Spec Stage 2 Clutch Kit Evo 05-07 (PM For Price)
Stage 2+
Types of Driving: Street, Drag, Road Race, Rallye, Pulling, Autocross
For all modified engines making more torque than the stage 2 can support. Maintains stage 2 feel for good daily drivability and offers very good wear characteristics, but provides a higher torque capacity. High clamp pressure plate, composite multi-friction carbon-kevlar material, high torque sprung hub and disc assembly, bearing and tool kit.
Spec Stage 2+ Clutch Kit EVO 03-07 (PM For Price)
Spec Flywheel
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.
