Any tricks to installing a Mugen Limited slip Differential?
Yes, the Mugen LS diff is slightly shorter than the stock unit and it will rub against a “rib” inside the transmission case. The solution is to use a pair of pliers to snap the rib off and file down the rough edges. Use 75w90 transmission oil. Break in the new diff by driving in a series of figure-eight’s in a large parking lot. Drain the transmission oil and replace with new 75w90. King Motorsports recommends Redline MT90.
