The Mantic Advantage

We provide all the necessary hardware like flywheel, bolts and alignment tool all in one package. The premium ceremetallic friction material and all billet construction make it more durable than stock clutch yet easy for everyday street driving and durable for street or track use. Pedal effort remains relatively low, approximately 12-15% increase over the OE clutch pedal feel. This Mantic Clutch kit uses our unique sprung center with cushioned organic twin discs. This equates to more torque capacity and heat resistance while retaining excellent drivability. The LSX swap twin disc clutches use dual 9in diameter discs that greatly reduces the MOI (Moment of Inertia). This allows more power to the ground as well as quicker more precise shifts. The lightweight flywheel revs quicker compared to the heavier OE flywheels.

The clutch is modular in construction for ease of service and is completely rebuildable. The billet red clutch cover and supporting components are machined from billet stock adding strength and durability. Billet will not flex under heavy pressure load like the typical weaker stamped steel kits. See Rebuild Pricing
