Twin Disc Clutch Guide Pt. 2

Attention:

You are installing a SOLID twin-disc clutch system, on a transmission that originally came with a DUAL-MASS flywheel that was originally designed to reduce chatter within the clutch system. When replacing the original equipment with a SOLID-DISC racing clutch, you WILL experience clutch chatter and louder than average clutch noise. THIS IS NORMAL! 

If you are a shop installing this system for a customer, you need to edify the customer as to what they are going to experience before they pick the vehicle up. 
With all racing clutches, this clutch has a lower than normal moment of inertia, as such it requires a different driving style that takes time to get used to.
