Hi All,

I am buying an OEM LSD for my 318IS.

Details are:

188 lsd oem 3.65 small case LSD

Some pictures







It's meant to be a genuine LSD from a 318IS. I've googled till I turn blue in the face and I can't see this ratio LSD for a BMW? The only real result showing is it could be a E9X motorsport LSD. So I'm a wee bit stumped.

Available ratios: http://www.bokchoys.com/differential/GearRatios.htm

I know it will work fine as I have been in the sellers (a friend, most will know) 318IS and it works. I'm worried it may be a bit tired I plan on new seals and oil (maybe plates) as preventative steps.

I'm not buying for sideways (well okay a little :tounge more for traction etc. So understandably I'd like to know what I'm getting as I've read once the small case goes it's done and cannot be rebuilt?

Any help please? Thanks
