With over 60 years of experience in manufacturing and designing clutches in Australia, Mantic Clutch has friction down to a science. Today we got a look at their full line of performance clutches, ranging from high torque stock replacements, to triple disc all-out race clutches.

Mantic’s street clutches feature a unique groove that is CNC machined into the face of the pressure plate – referred to as the ER2 Groove Design (“Effective Radius”). The ER Groove Design removes friction material from the face of the pressure plate to move the mean effective radius further out, which subsequently gives the clutch more holding power (up to 8% more torque capacity).

Those funky grooves in the pressure plate help increase the clutch's torque capacity by as much as 8%.

Stepping up to the Mantic MOI (“Moment of Inertia”) Plus series of multi-disc clutches gets you an even higher level of engineering details built right into each clutch. The “Moment of Inertia” refers to an object’s resistance to changes in its rotation, so with a spinning clutch you can imagine that a lower MOI is a very good thing since clutches need to both accelerate and decelerate very quickly. Mantic’s MOI Plus multi-disc clutches have material removed from the outer edges to lower the clutch’s moment of inertia, and to decrease the overall mass.

Even the case your Mantic MOI Plus Clutch comes in is superb quality...

Mantic prides themselves on the manageable pedal effort required to operate one of their multi-disc clutches, and we were privileged enough to get to test one out for ourselves in the awesome Holden Commodore road-race car on display at their booth. The clutch felt very streetable – truth is, driving on the right side of the car would be harder to acclimate to than the effort of Mantic’s race clutch. Check out Mantic’s full line of LSX and late-model performance clutches on their website.

This Holden Commodore is one of Mantic's track mules, featuring a relatively stock 6.0L LS engine.
