I need to replace the LSD on a 1995 (NA series) MX-5. The original diff was a viscous LSD, and over time has deteriorated as I hear they do. It is now essentially an open diff, if I lift one wheel off the ground it seems to apply torque only to the lifted wheel, and I would like to replace it.
I have seen that there are a few different types of diffs available, and of these they come in 1, 1.5 and 2 way varieties. The 2 way diffs seems to be more expensive in general, and I would like to know in what instances will having a 2 way over a 1.5 way be an advantage? 2 way to 1 way? In what applications would having a 2 way be a disadvantage?
