The M-Pact ST1.5 Upgrade Clutch Kit features a high torque multi-friction disc and is perfect for mildly modified vehicles or aggressive drivers with stock power. The multi-friction disc is unique because it incorporates two different friction materials working to achieve maximum performance and drivability. A steel back lining is used on the flywheel side for smooth engagement and less flywheel surface wear while a segmented sintered ceramic facing on the pressure plate side delivers maximum holding power.
Features:
- Offers a 20-40% increase in torque capacity while maintaining a stock pedal feel
- Features a matched pressure plate with a heavy duty multi friction clutch disc
- Incorporates two different friction materials working to achieve maximum performance and drivability
- A steel back lining is used on the flywheel side for smooth engagement, less flywheel surface wear, and delivers increased burst strength and better heat dissipation
- On the pressure plate side, a segmented sintered ceramic facing delivers maximum holding and increased grab due to the disc marcel
- Precision engineered, heat treated hub, HD retainer and hi-torque springs

 Organic vs. Kevlar vs. Ceramic Friction Disc - What Is The Difference? The Friction Disc is a vital part of any clutch. It connects the pressure plate and flywheel, and is responsible for transferring engine power to the rest of the vehicle. Clutch Kits come with several different types of friction discs, and it is important to understand the pros and cons of each material:

 Tips & Tools For The Job - Wear a Dust Mask to protect against hazardous clutch dust. You can also spray the clutch with water prior to removal to reduce the amount of airborne dust during disassembly.
- Use a Flywheel Turner to hold the flywheel in place while removing and reinstalling the pressure plate bolts.
- Apply Blue Threadlocker to flywheel bolts prior to installation to prevent backing out due to the high vibrations flywheels are subject to.
- Use the provided lubricant to lightly lubricate the splines of the input shaft. Over lubricating the input shaft risks lubricant transfer to the clutch friction disc and can cause clutch slippage.
- Be sure to install the new clutch friction disc in the correct direction. The disc will have a "Flywheel Side" label on one side.
