so the basic unit itself is a great basis but it comes as standard with a pretty low locking setup and wears out quickly.
I've got an e39 m5.. mostly street use & aggressive backroad driving -- track day 1-2 times per year. What would you suggest for this type of driving? (i'm sure at 140K on my odo that my diff is shot-- any quick test?)
