OS Giken LSD

Anyone have a OS Giken LSD installed in their car and use their car as a daily driver? And is there anyone with the LSD located in San Diego?

Hey guys, cross posting this from another subsection in case someone knows more here.

I've been doing some research on the OS Giken Superlock LSD for a 2010 E90 335i steptronic which I believe is a small pumpkin, bolted diff. According to the osgiken.net website, the BM531-HA will fit an E90 auto trans (BMW-L2(A)). But I've seen from some other resellers that they don't make one for the 2007+ auto diff (small pumpkin), is that true? On the other hand, I have actually seen a post from someone who had the TCD version (not superlock) on a late model E9x auto, but can't seem to find that post again... not sure how he did that.

If there is a Superlock that fits, what is the model number, because surely the BM531-HA cannot fit both the big pumpkin and the small pumpkin??
Any help appreciated!
