Clutch Masters 97-03 BMW 540I 8 Cyl 4.4L E39 Lightweight Aluminum Flywheel

Lightweight aluminum flywheel 267mm Upgrade.

Clutch Masters Flywheels are designed and tested to ensure the safety and quality of every flywheel. Years of R&D has given us the knowledge and firsthand experience to choose wisely the best material to manufacture flywheels that will surpass your expectations. Depending on the application, the majority of Clutch Masters flywheels are made from 6061 T6 Billet Aluminum. Clutch Masters Flywheels are SFI Certified meeting performance standards for the automotive and motorsport industry.*

*Benefits of a Clutch Masters Light Weight flywheel:*
* Light-weight for improved performance and Quicker Rev’s.
* Reduces turbo “lag” in turbo-charged engines.
* Increased supercharger efficiency due to less drag on the crank.
* Improved mid-range torque in naturally aspirated engines.
* CNC Machined and balanced.
* SFI Certified.

*Replacing your OEM flywheel with a lightweight flywheel may cause gear noise or a vibration that may not be suitable for everyone. The lighter the flywheel the more gear noise will be produced. Depending on the application Clutch Masters usually recommends Steel flywheels rather than Aluminum flywheels since Aluminum flywheels will cause more gear noise. Aluminum flywheels are usually only recommended for race applications looking to have the least amount of weight as possible. A lightweight flywheel may affect the life expectancy of a clutch kit depending on the application.

*Going from a Dual-Mass Flywheel (DMF) to a Single-Mass Flywheel (SMF):*
A Dual Mass Flywheel (DMF) is a flywheel in two concentric parts or two facing flywheels stuck together with flexible compound to damp down transmitted vibration and gear rattle for the gear box. Many newer model vehicles now come standard with a factory DMF. Many times enthusiast choose to replace a DMF with an SMF and here is why:
* DMF’s tend to be more expensive than an SMF.
* DMF’s are not designed to be resurfaced like conventional SMF.
* DMF’s usually weigh 30+ lbs depending on the application which will cause unwanted turbo lag.
* DMF’s cannot withstand a high rate of abuse and may fail under spirited driving.

*Benefits of switching to a SMF:*
* Reduced mass equals increased acceleration.
* Reduces turbo “lag” in turbo-charged engines.
* Increased supercharger efficiency due to less drag on the crank.
* Improved mid-range torque in naturally aspirated engines.
* SMF’s are able to be resurfaced and can be reused.
