E90 320si compatible LSD?

[Josepiii]

Hi new to the forum

Currently planning a 320si build and wondering if there are any compatible aftermarket LSDs currently in the market?

Love that the engine was homologated for the WTCC - I really geek out on that kinda stuff - so don't mind that it's not got as much grunt or character as the 6 cylinders. I'm also aware of the the issue with cracked cylinder heads and happy to do some work to prevent any failures.

So far I've found a number of LSDs that are compatible with the E90 325i, 328i, and 330i such as the Wavetrac LSD l, but I'm unsure if this will work on the 320si.

I don't have loads of technical knowledge so any advice would be great thanks ))

Thanks @firefly96!

Just found a compatie helical LSD from Quaife. Birds are their main dealer in the UK - £919 for the diff, £1392 with fitting.

Birds will take care of ya. Their E9x suspension kits were also rather good.

The 320si is very cool, I've seen only one in person! Share your progress with it in the E90 forum if you want.
