After entering my rat-racer 'Project Bratwurst', BMW E34 525i into the PPC challenge it was built for this year it soon became very much apparent that it needs an LSD! Traction in first gear was non-existant and second wasn't great.
So, my question is, what options for LSD donors are there? I've already concluded that E36 diffs are unsuitable unless I wish to dismantle and reassemble the diff into my casing and setting the pre-loads.
To keep things simple, first of all which E34 models came with them fitted?
As a back up, will any others fit such as E30 or E32?
Thanks for any help.
