Question What LSD fluid do you use for your street ti?

As the title says, what LSD fluid are you using in your street ti? I was lucky enough to pick up a small case 3.45 LSD from Dan and will plan to install it this weekend. I looked through various threads, but there was no clear answer other than fluid weight. I figure our responses can help other folks with similar questions in the future.

I see 75-140w for LSDs, although a 75-110w is used by some folks to keep heat down. 75-90w seems to be the spec for non-LSDs, although some folks are using it in their LSDs without apparent issues.

Dan mentioned he used Redline, which I have used in my non-LSD diffs. Not sure if a LSD modifier needs to be added to Redline.

What do you use? Whatever you use, do you hear any difference when you are driving? I ask as I tried Royal Purple when I could not find any Redline at one point in another non-LSD BMW and I experienced a whine when underway. Not sure if was due to the fluid change or if the properties were different than the BMW fluid. I went back to BMW fluid and the whine went away. Never was really sure what went on there.

Also, can you mention if you are running a LSD or a Torsen diff and if a LSD, is it a small case 3.45 or a E30 or other variant?

Anyway, thanks for your feedback! Rich
