Well I broke my Main Cap in my Diff and was wondering if anyone is using a diff that isnt stock? Which differential is better than stock and Since the dealer said I need a new carrier or housing since it machined for it I was wondering why not upgrade (which the bright idea was given by Kevin :biggthump) What else would be needed if went with a new diff? Does it come complete? I was looking into a Detroit Locker diff? Anyone has heard or used these in a 03/04 Cobra? Let me know thanks guys.
