Spec Clutch SZ03A Spec Sz03a Aluminum Flywheel

Aluminum Flywheel

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 flywheels 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 cars output and performance.

They have the best prices on the net hands down. I saved 40 bucks buying through them and not only that but my item was shipped promptly. I would recommend using them i know im coming back.

Best Price! and quick shipping A++

quick and easy

Easy, easy, easy

Some parts have very limited information such as left or right or if ball joint is included and so on, other than that the prices and shipping seem fair and the web site is easy to navigate. Thanks Dave

all good

Fast and easy

Great experience! I placed my order on Sunday and my programmer arrived on Thursday - with ground shipping. I unpacked the programmer and it functioned exactly as I had hoped. I will definitely consider purchasing from Autoplicity again!

Thanks.

Quick and easy.

User friendly

Lowest price I found on the Web. Super fast order processing and delivery! It's a pleasure doing business with such a reliable<br>merchant. I'll look here first for all my future auto needs!
