i have just installed a king cobra clutch on my 01 GT. i have heard that you have to drive a certain number of miles to break it in properly. is this true? and if so how many miles? also about how much of a life span can i get out of this thing?

 

just drive it.

Clutch life is dependant on your ability to properly drive a stick. I know guys that make them last 25K, and others that have 130K and still on the stock clutch.

Breaking in a clutch is kinda dee-dee-dee. It's either engaged and locked up or not engaged at all. It's not like it's a brake where it continually grinds away while you're moving.
