What’s Included
  • Unsprung MIBA Ceramic 6 Puck Disc
  • Single Diaphragm HD Pressure Plate
  • Pilot Bearing / Bushing (when applicable)
  • Clutch Alignment Tool
  • Conventional Release Bearing

Break-in Requirements
500 street miles / Keep RPM’s under 4500, no more than half-throttle, no boost (if applicable).
Proper break-in is required in order to retain product warranty, ensure longevity and holding capacity.

Disclaimers
Ceramic based clutch discs intend to increase the holding capacity and durability of the clutch as opposed to an increased life expectancy. Using a ceramic based material for easy street driving may contribute to premature wear of the clutch kit due to the harsher engagement and because of the higher tendency to slip the clutch during street driving.

Using a clutch kit with an unsprung clutch disc on a stock or lightly modified power engine that is daily/street driven vehicle can break the rivets on the clutch disc hub. Unsprung clutch kits are not designed for daily/street use or any constant on/off engagement environment. This can be compared to running a marathon in sandals vs a proper running shoe. If you were to run the marathon in sandals, you have no cushion or comfort and can cause injuries or wear you down faster than using proper running shoes.

*Increase in holding capacity is rated in Crank Torque, not Wheel Torque

low-maintenance shirt that fits perfectly
Color: Black, Size: 3X-Large
This COOFANDY Casual Button Down is a fantastic addition to a summer wardrobe, offering both great fit and high quality. The material is impressively wrinkle-free, which keeps it looking sharp and crisp even after a full day of wear. It is specifically designed to be worn untucked, and the length is just right—offering a modern, relaxed silhouette that doesn't look sloppy. The fabric feels durable yet breathable, making it comfortable for both casual outings and slightly dressier occasions. If you’re looking for a low-maintenance shirt that fits perfectly right out of the wash, this is an excellent choice.

My husband loves these shirts
Color: Dark Blue, Size: Large
My husband just loves these shirts. He has one in every color, I think. Great quality, good price, breathable, true to color, and super comfy. Nice enough to wear to a nice dinner but can be dressed down w a pair of shorts and flip flops. By far the best find I have found!

Shrink-wrapped shirt???
Color: Clear Blue, Size: X-Large
This shirt arrived in a vacuum packed clear package which caused wrinkles in the synthetic material. Instructions to remove the wrinkles are to run the shirt through a wash cycle. Well, that didn't work! I'm hoping a dry cleaning service can steam press the wrinkles out. Aside from that issue it is a very nice shirt. Sizing good. Fabric thickness and material are very good. Because it is made from polyester and spandex shrinkage will not be an issue.
