Q: Any tricks to installing a Mugen Limited
slip Differential?
A: 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.

Suspension Questions
Q: I want stiffer front torsion bars.
A: Are you sure? Unless your car is a dedicated
racer, or you have put a heavier engine in, the stock torsion bars
are stiff enough in the front. People who have put stiffer front
torsion bars in their cars report that the ride becomes very hard
and uncomfortable for daily driving. You can buy thicker, stiffer
torsion bars from OPM Motorsports, they sell 22mm and 27mm torsion
bars. Check the list lower in this section for torsion bar and sway
bar choices.
