Been looking around for a new clutch to throw in with my new J4D LSD tranny and the main differences I have come accross are the number of pucks, the material the friction pads are coated wtih and whether or not it is sprung. Some clutches have 8 pucks and some have 6, some are coated with miba and some with kevlar, and some are sprung while others aren't.

Whats the difference with the pucks? From what i've read, the less number of pucks you have, the more aggressive the engagement will be, and that this is not good for a daily driver. That would be more for a track only car. Is this true? Someone told me I could get away with a 6 puck for a daily driver, but that I would only need that if I was going to be making really big power. My goal is to hit around 250-300 hp when I eventually build my engine and boost it. Could I get away with a 8 puck or should I go with a 6?

As far as the friction pads go, does it really make a difference whether it is Kevlar or Miba? I heard that kevlar will last alot longer, and someone also mentioned that I would get less "chatter" with miba coated (i have no idea what chatter means). Is this true? Anyone have an opinion on that?

And the last thing is the sprung vs unsprung. I'm pretty sure that I know what this means. A sprung clutch will have less holding power but be easier to engage and disengage, but an unsprung clutch will have significantly stronger more agressive holding power but would put more stress on the tranny and be harder to engage/disengage. Right?

Any help and input would be greatly appreciated. Thanks!
