Yes, they came for sale locally and I jumped on them.

With respect to the “S,”. If that means Sphere then what does the white “A” stand for on the open differential I pulled off the Verty30 mean?

"absolute garbage" haha

Throw some smilies, euro bumpers and do a little drop and that vert will look so awesome, not that it doesn't look good already!

wheels look great. you found those really fast.

the "s" on the top of the diff means "sphere" which is auf deuche for limited slip.

Had an epic day with the Verty30. First, I had to button up the rebuilt 3.73, then pull old Open diff then bolt in the 3.73.
Interesting find when I cleaned the old diff that I pulled off The Verty 30. There is a white “A” painted on top of the differential casing at he same location where the “S” is painted on the rebuilt 3.73 that I put in. I know everybody out there in BMW land swears that the “S” means that it is a LSD unit. I’m not so sure that’s true. Me thinks that “S” means it’s a standard or manual and the “A” means it’s from an Autotragic. The Verty30 is a five speed and the unit I pulled off was a replacement unit the original owner put in a while ago.
Also, I know the unit I pulled off is open but I’m trying to figure out its ratio. I indexed the input and output flanges and the input flange spins approximately 3.25 to 3.50 times for every out put rotation. However, based on the rpm output I’m thinking its a 3.73 open. More to come on that...Here’s some photos:

Good luck getting the backlash set on that diff... I could never get mine right.

Today the Verty30 Differential Swap happens...standby for the drama.

haha you got balls deep into that diff! It should make the car more enjoyable once you're done. Good luck!

Update: Today I replaced the friction plates and dog ears inside the Rear Diff Clutch carrier. Not a bad job just had to be detailed oriented to make sure all the components, especially the belleville washers, were correctly placed. I then replaced the large o rings and the output seals on the flanges. Took a few hours and I really enjoyed it. Had the Jet game on and reveled in their loss and the Eagles win. Here a few photos. Notice the old friction plates and dog ears at the top. The friction plates definelty were tired and the dog ears were mirror shined.:

Tonight, I have limited time before taking my son to a catching clinic. So I cut the center of the rear differential bushing out and will start on carefully cutting away the metal bushing ring.
