just did a full delete and stage 2 tune and am starting to look for a limited slip.
what rears are compatible?

09 e90 peasant trim level

Not looking for a world beater- have other fast cars. Even though this is just a commuter the traction light looks like a pinball machine

The only E90 to have a factory rear LSD is the M3's (1M would technically be the same)

read my thread please. I fitted a wavetrac LSD into a 2.81 diff. I wouldn't mess with the M3 unless you want a way higher final ratio.

You were wrong. At least not from the factory.

the "E-LSD" uses the rear brakes to lock up a side and shift power for grip. That isn't anything close to having a differential lock up so both wheels receive the power transfer

E-diff pretty much sucks. It actually gets you into trouble if you're trying to accelerate and it puts you "dead in the water" temporarily.

100% agree; That's why I bought an actual LSD. It 'CAN' help you in winter situations but you gotta turn off Traction/Stability to make use of it

Thanks guys. Not worth it to me to chase down and fit a limited slip. Guess i will just spin 550 torque. deleted and tuned this thing has potential for sure.
