Clutch Material

You will get efficient and thoughtful service from NFJ.

Your clutch lining material will be Organic, Ceramic, Kevlar or Feramalloy.

Organic is the choice of most OEMs. Organic offers durability, smooth engagement and are gentle on matting surfaces. The downside is they do not like heat and require a fairly high clamping force to maintain grip as the co-efficient of friction is only around 0.32. Organic friction discs will almost always be a full face discs with the organic material made from phenolic resins, metallic powder or metal oxides and moulded or woven in construction.

The heavy duty options will have more metallic material in the mixture and also have a pressure plate of higher clamping value.

 Kevlar like organic needs a fairly high clamping force due to it having a similar co-efficient of friction to organic. Its advantage is its ability to withstand heat. Often Kevlar is able to withstand 40-50% more heat than organics. Just like organic Kevlar offers smooth engagement and minimal wear of matting surfaces. This friction material will often last two to three times longer than the organic option. These are a good option for slightly modified vehicles and off road use.

 Ceramic offers the highest co-efficient of friction of all the materials coming in at 0.48-0.55. This means that they can be used with a lower clamping force pressure plate and or high output applications.  Ceramic clutches are known to wear mating surfaces heavily. This wear also makes them shudder on engagement. They can take more heat but slipping will cause heavy wear and result in a burnt up pressure plate and flywheel. The material is a mix of sintered bronze, ceramic material, copper, tin, iron, silicon dioxide and carbon. These are the competition clutches. 

Feramalloy is a newer material and will possibly replace ceramic facings. It offers similar levels of wear and temperature resistance to ceramics. The advantage is it has a better static to dynamic ratio. What this means is smoother engagement and less shudder or chatter than ceramics. 

I just have to add carbon carbon. In this setup both the friction material and the matting surfaces are amorphous carbon.  This material grips more as it gets hotter and is extremely light. Cost of  production is very high and these tend to be only a top level motorsport item. A good compromise is to use a carbon clutch disc, steel flywheel and pressure plate. 

Single and twin plate clutch set ups  is a story for another day.

At Mantic Clutch USA we offer two main types of clutch material, organic and ceremetallic. Each of the materials serve a direct purpose for driving style and horsepower range. Both are friendly on the street and allow a strong advantage over the stock OE style clutches. Lets go over a few of the features and benefits to help determine which is best for your application. 

Organic 

Perfect for the everyday driver with more power than stock offering smooth engagement and release. An organic clutch will stand up to hard use, but it won't be able to take repeated heavy abuse because it will overheat. If you track the car frequently, choose the ceremetallic material. Break in period is around 300-500 miles. Features more torque capacity and heat resistance than stock while retaining excellent drivability and its easy on the leg. Great for N/A, turbo, supercharger or nitrous depending on usage.

Torque Capacity at Crank: 600

Torque Capacity at Wheels: 500-525

Ceremetallic 

More aggressive than organic but it serves the purpose with higher capacity and more durability. This is our most popular option and is the favorite friction material for those who drive their car daily yet head to the track on the weekends. Most who choose the ceremetallic option are normally forced induction, nitrous or turbo applications, even the bigger N/A cars frequently choose this more durable option. 

Pedal effort remains relatively low, approximately 12-15% increase over the OE clutch pedal feel yet the strength in material is still capable for any heavy duty usage. Due to the type of material, this clutch will almost bite down instantly, perfect for quick precise shifting to help maintain RPM levels and keep power to the ground. Break in period is 500+ miles, depending on driving conditions.

Torque Capacity at Crank: -

Torque Capacity at Wheels: 820-850

Which Clutch Should I Buy? 

When choosing a clutch you should always select the friction material that fits your needs based on power levels, type of driving and future goals. Our organic material will handle a wide variety of uses, including daily street driving and with limited racing. Ceremetallic is the most durable option for the serious builds that require the best clutch without upgrading to a full race style system. If your running a supercharger, heads & cams, single/twin turbo or even the fun loving nitrous, we suggest running the ceremetallic material!!
