Thank you.
Backdraft Parts - Limited Slip Differential That seems pretty high, considering I could buy a new Powr-Lok on ebay for less than $500. What is it that justifies that kind of cost on a BDR? Or, put another way, why does a BMW rear cost two grand for what seems like a pretty straight forward, common upgrade?
