The 535i sport came with an LSD so I presume the 525i sport did as well so you should be able to swap out the standard diff with the lsd from the 2.5 sport model (or even the 3.5 if it fits).

Or even cheaper and weld up the open diff. Perfectly usable with it welded, just a bit more understeer. It's what most drifters do on a budget.
///M diffs are only 25% locking anyway, you can modify the ramp angles and add more plates but welding costs virtually nothing.
