i bought mine through summitracing, only problem with centerforce is youll have to buy a new T/O bearing and Pilot bearing seperately, and an alignment tool if you dont have one, they dont have a kit

and theyre a bit pricey, but they are awesome


if your going for cost, King Cobra might be up your alley

 

centerforce dual friction! I think I bought mine from brothersperformance. here is a link for the install to give you an idea: http://www.cartechbooks.com/vstore/s...5&CATID=21
