I have been reading on here that the LUK clutch kit is the one to use on the TJ. Why is the LUK clutch so highly recommended and what would be my part number for my 2000 model sport with the five speed? Also in my quadratech book they have the center force clutch kits that have different "stages" 1,2and 3. What makes the LUK better than the center force clutches??
