Just installed my Limited Slip Differential from roscoeuroparts.com on my 2020 540i RWD

First Impressions are wayyy better than the garbage open diff. Handles like more like an M car and not a boat making it more predictable. Definitely feel the difference behind the wheel. Also way easier to spin the car.

Was a struggle to install, although I did not have a lift so used jackstands! With the help of Blake Roscoe & Peter Harold I was able to follow the video and it was manageable. Took my time with install but got it done.

Definitely recommend for anyone who wants to improve handling or if you’re diff is on its way out. Great customer service and great price.

Only other option for our cars is from birdsauto, the quaife lsd which is way more expensive around $3,100 and you gotta send your old diff in for the core they keep while roscoeuroparts you get the entire unit shipped to your door while paying less and have the option to keep your old OEM differntial or sell it.
