yeah, i almost bought a nismo one, but the price of the Kaaz you just cant go past. as for the clunking, you get used to it. when i first put it in, the noise was so bad that i pulled it out and took it to a diff shop and asked if it was alright. they said that it was fine and that it would get better as time went on. now its pretty good. sure its a little noisey when its cold, but once its warm its actually pretty good. but your gonna get that mechanical slipping noise with any mechanical LSD you buy....
i'd be happy to take you for a ride one friday night soon, but not this friday, as im playing with the car...
