K-Factory UFO 2 White Clutch Shoe
Taiwanese company K-Factory have released this UFO2 white clutch shoe for use in Centax type clutches. This high grip clutch shoe has a special high friction surface which means the clutch engages the moment it comes in contact with the clutch bell making it very useful on high traction circuits where you may have a very high engagement rpm setting for maximum acceleration. When set up correctly, in high traction, this type of clutch shoe can help the car accelerate very quickly.
