Hey guys,

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 other sites like VAC that they don't make one for the 2007+ auto diff (small pumpkin), is that true? 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?

Are there any other clutch plate LSD options for the car? Any info most appreciated, thanks.
