After years of Research and Development to correct the poorly engineered and undersized OEM BMW E39 M5 clutch, we are proud to present the best clutch package offered on the market today. Here are some of the advantages to the CNS Racing E39 M5 Power Clutch Kit.

- The CNS Racing BMW E39 M5 Power clutch kit offers the best of both worlds - An oversized 10.5 inch complete Power clutch kit including a ligtenend and balanced Dualmass flywheel design. Unlike the competitor clutches which include a lightweight and noisy (gearlash) single mass aluminium flywheel, the CNS Racing kit includes a lightened dualmass flywheel which offers Zero gearlash/rollover noise and no chatter just like the OEM setup.

- The clutch component diameter has been increased in size from 9.45 inches (240mm) to 10.5 inches (267mm). This provides greater surface area for much greater clutch durability and heat dissipation.

- CNS Racing only offers a full face carbon semi-metallic clutch disk which has proven longevity and identical OEM streetability. This in turn eliminates the chance of clutch disk glazing which occurs in OEM and competitor kits that have an Organic disk lining.

- Identical if not better OEM pedal and engagement feel.

- Completely plug and play just like the OEM kit. A clutch stop is also included in the kit to adjust the pedal engagement point.

- The OEM SAC mechanism has been eliminated for clutch reliability.

- 800+ rear wheel torque capacity. Great streetability and Racing use. Perfect for Supercharged M5 applications as well.

- The Dualmass flywheel is lightened and German quality.

- It is a complete kit including the streetable high clamp pressure plate, full face carbon semi-metallic disc, OEM release bearing, clutch stop, and lightened dualmass flywheel.

Why incur the cost of reinstalling poorly designed OEM and competitor clutches plus the expensive labor for installation. Save thousands of dollars with the CNS Racing E39 BMW M5 Power clutch kit by installing a clutch once! No more babying a high performance car in fear of burning the clutch. Drive your M5 the way it was meant to be driven!!

Rogue Engineering is proud to partner with JB Racing to bring you the most inclusive and highest quality line of clutch systems available. In the past, we have used multiple flywheel manufacturers, constantly improving the design and quality. JB Racing Lightweight Aluminum Flywheels are designed and manufactured to the same exacting standards and precision our customers expect and offer unique and significant features not found in competitive brands.

There are significant benefits of an Rogue Engineering Performance Clutch System (PCS) over a factory dual-mass flywheel setup are numerous. Some benefits include:

-Lighter total weight, allowing engine to more rapidly transfer power
-Longer lasting friction materials
-Elimination of SAC (Self Adjusting Clutch) mechanism on factory pressure plate
-More consistent, predictable clutch engagement
-Ability to handle more power than factory setup.

To appreciate the some of these benefits of the Rogue Engineering PCS, we will cover the details of the components.

The Big Deal on Flywheels
The drivetrain is the key for marrying the power from the motor to the wheels. A key components in this transfer of power is the flywheel. Using an aluminum flywheel in place of the factory part (generally a heavier, dual-mass unit) can reap some benefits, but if improperly designed or manufactured, can produce detrimental results.

It is no secret that an aluminum flywheel can weigh as little as 1/3 of the weight of a factory dual mass unit. Because the flywheel resides on the end of the engine crankshaft, a unit that is too light can cause premature synchromesh wear, excessive low end clutch chatter, or worse, possible engine damage. Excessively lightweight flywheels also lack initial inertia, causing the car to stall when the RPMs drop near idle. These are some of the reasons why Rogue Engineering's PCS does not strive for the ultimate lowest weight when it comes to the flywheel. For example, our E36 M3 flywheel replacement still weighs over 10 lbs. (compared to the factory 24 lbs.).

Flywheel Construction Details and Features
Rogue Engineering has used multiple flywheel manufacturers in the past, constantly implementing improvements the design. Finally, in collaboration with JB Racing, our flywheels now implement some unique features not found on other designs:

-CNC machined to factory dimensions for a exact fit
-Replaceable, hardened, heat-treated steel friction surface
-Helicoil inserts for pressure plate bolts (prevents bolts from stripping)
-Enlarged dowel hole, like factory flywheel (where applicable)
-Flywheel gaul plate and replacement 10.9 flywheel bolts
-Replacement pressure plate bolts
-Completely zero balanced
-Manufactured to exacting specifications, to accept our patented semi-metallic backed sprung hub disc

Whereas many manufacturers "claim" to balanced their flywheels, most do not. Spinning a flywheel to 10,000 or even 14,000 rpm does not magically balance it. As an example, nobody would ever consider using a wheel/tire without dynamic balancing them together since it would cause the steering wheel to vibrate terribly at speed. Since the flywheel is the first item bolted to the end of the crankshaft, this makes is even more important that it is completely and thoroughly balanced. Ask any engine builder assembling a high performance engine if they would risk installing an unbalanced, rotating mass on the end of their newly assembled motor. We think the answers you will get will be pretty clear.

It is important to know that even 100% CNC products of this mass ALL require some level of balancing. Typically, this is necessary to compensate for variables such as assembly hardware, dowel holes, dowel pins, and friction surface variations. Regardless if it is only 1 gram out, all flywheels require balancing to eliminate potential annoying and sometimes destructive vibrations. Therefore all flywheels we sell are “zero balanced” as standard without any additional cost.

The Return of Old Reliable
All Rogue Engineering Performance Clutch System eliminate the need for LUK-manufactured "SAC" pressure plates. These SAC (Self Adjusting Clutch) pressure plates tries to keep the clutch engagement point at the same place, compensating for clutch disc wear.

In theory, the SAC pressure plate is a noble idea for those that do not have experience driving a manual transmission. The mechanism tries to maintain the same clutch pedal engagement height at all times while compensating for clutch disc wear. For those that have manual transmission experience, it causes frustration as it compromises true clutch engagement and feel. Another downside of the SAC system is that it does not allow for full clamping force especially when the disc starts to wear from stock thickness. The Rogue Engineering PCS eliminates the use of the SAC pressure plate and uses a more traditional style pressure plate allowing the clutch system that allows for 100% clutch engagement that can be modulated.

Plenty of Power
Regardless if your BMW is bone stock or highly modified, the Rogue Engineering Performance Clutch System has been used on vehicles of varying levels. No worries about a flywheel that is too light, which may flex under power, causing uneven wear. It's as simple as choosing the appropriate power stage for your application. From our Stage 1 to Stage 3, we've got a solution for your BMW. In case you require even MORE, you can contact us for a custom solution.

A Match Made in Heaven
Starting with the highest quality available single-mass aluminum flywheel is only the beginning. Matching the appropriate disc and pressure plate is also an important aspect of the Rogue Engineering Performance Clutch System. By choosing the desired power requirements, you are assured the appropriate disc and pressure plate while maintaining street drivability.

Not just for Naturally Aspirated BMWs
Turbocharged and supercharged vehicles can also benefit from an aluminum lightweight flywheel. Turbocharged engines that have to build boost due to turbo "lag" are now finding the ability to transfer power sooner with the decrease in rotational weight. On a supercharged vehicle, a lightweight flywheel reduces parasitic drag at the crank, improving efficiency.

Idle Rattle Resolutions
With the replacement of the dual mass flywheel with an aluminum version, the spring mechanism which absorbs the driveline vibrations is no longer present. When using a stock, solid hub factory clutch disc, this can lead to annoying rattling sounds at idle. This idle rattle can sound like loose bolts in the transmission, and even worse, if the A/C compressor is turned on. Worse yet, is the cabin resonance at specific RPMs, which never improve or go away.

Rogue Engineering pioneered the concept of a sprung-hub clutch disc to help alleviate this issue. While the sprung hub mechanism in our custom built, sprung-hub clutch discs can reduce, minimize or even completely eliminate these typical noises, its cannot replicate the job of the heavier, dual mass flywheel.

-LIGHTWEIGHT OPTIONS : SPEC's Lightweight Option can be added to any clutch for £79.
SPEC manufactures aluminum pressure plates for many applications. These pressure plates are designed for OE fitment, but can be used with an array of transmissions and flywheels. The benefit of the aluminum pressure plate is comparable to gains from a lightweight flywheel, and in most cases is less costly.
For years lightweight flywheels have been used to transfer energy from an engine to the ground more efficiently, resulting in horsepower and torque gains, quicker revving and less internal engine wear. The SPEC aluminum pressure plates offer the same benefits, and the reduction in mass is more effective since the pressure plate extends further from the crank flange.
These plates can be used with an OE flywheel or in conjunction with a lightweight flywheel for a more drastic improvement. Drivability is virtually unchanged, and the aluminum plates offer the same high clamp loads, and in some cases more clamp load, than the standard steel SPEC high performance pressure plates. SPEC uses only aerospace quality aluminum and fasteners and most SPEC aluminum pressure plates carry SFI certification.

Please refer to the on line price list below and it's listed torque capacities for each clutch option and then e mail or call us to make your order.
