Lightweight flywheels are a great way to add performance to your Boxster. They are designed to reduce as much weight as possible but not sacrifice any drivability. If your Boxster needs a clutch, you are already inside the engine and a change to a lightweight flywheel is simply the cost of the part.

-Lightweight 6061-T6 billet aluminum (only 13 lbs!)

-CNC machined to .001"

-Wear-resistant, replaceable treated alloy steel friction inserts

-Stepped Dowel Pins

-Torque plates included in applications where required

-Works with both stock or aftermarket clutches

-The broadest range of applications available

-High quality polished finish

Aasco's aluminum flywheels have some key advantages over stock and other aftermarket units. Machining tolerances are extremely important when making a flywheel. Eccentricity, parallelism, and the step height (which is critical to proper clutch break-in and engagement) are kept to within .0015”, the most accurate in the industry! Dowel pins are hardened steel units and all hardware is grade 8 (grade 10.9 metric equivalent), the highest grade of fastener available today. Torque plates are also included in applications where required and flywheels are checked for zero-balance before shipping.

NOTE: The Flywheel Seal, or known by many as the notorious Rear Main Seal (RMS), is known to be a weak leak in the drive train of the 986, causing oil residue to seep and eventually leak out into undercarriage and garage floor. It is HIGHLY recommended that you replace this seal if you notice even the smallest amount of oil seeping out between the transmission housing and the engine block. In some rare cases the RMS has been known to fail more than once in less than 10,000 miles of driving. If you are tackling a clutch job, you should definitely consider replacing this seal while you're in there.
