Continuing with the LSD. It didn't feel right to put it back in standard. I always planned to replace the clutch plates but why stop there... So I did lots of research into how I can improve it's lockup and effectiveness. Standard they are a 2way 25% lock up diff. I found a place called Difflab who specialize in BMW LSD work. So I sent the thrust plates away, where the ramp angles were cut to a new angle, friction surfaces re finished, followed by heat treating and glass bead blasting. This has turned it into a 1.5way diff with 40% lock up.
Before:
Now:
New OEM friction/clutch plates. The old ones had no grooves left in them, so definitely warn out.
Old ones:
As well as new alloy steel plates designed for increased service life and harsher bite:
Old ones were also grooved and worn out:
Definitely learning lots about LSDs and how they work throughout this process.
