E36/E46 M3 Diff Cover Washer Upgrade Kit

E36/E46 M3 Diff Cover Washer Upgrade Kit Overview This upgrade kit is for all E36 and E46 M3 running our polyurethane 80A or 95A differential cover bushings! Polyurethane bushings are a great upgrade in performance while being compliant enough to be a good compromise on the street. Most race cars and pro level drift cars all run solid differential bushings, just ask our FD driver Rome Charpentier! However, solid bushings might be a little difficult to live with for those who street drive their cars. That's where this upgrade kit comes in to give just a little extra bit of performance over the standard polyurethane differential cover bushings without sacrificing any of the street comfort that we love about polyurethane over solid bushings. Sold as a kit of two, no additional hardware needed to install. Simply remove the bolts from your existing poly diff cover bushings, place the washers in and torque back to spec! Why should you upgrade to this washer? We drive our E36 and E46 M3 ha
