Nope, the M3 is the only 3-series to come with an LSD.

How do I identify my BMW differential?
The numbers you need to identify your diff are on a small metal tag attached to one of the rear cover bolts. The first three numbers will be the ratio (e.g. 3 45 xxx..) , or if the numbers are preceded by an ‘s’ (e.g. S3 45 xxx..) then you have a limited slip diff.
What is a BMW rear differential?
Function of the Rear Differential The rear differential is the part in your BMW that takes the torque from the engine and divides it to the left and right wheels. When the torque is split to both wheels, they will be able to spin at different speeds.
Does my BMW have limited slip differential?
With both wheels in the air spin one, if the other spins the opposite direction it’s an open diff, if it spins the same direction it’s a LSD. Try sliding it and if you feel the inside wheel spin faster or outside one do something different than its a open diff.
Is locking diff same as limited slip?
An automatic locking differential can unlock and allow the inside wheel to rotate freely, but only when power is limited. The limited slip differential will allow some slipping between the two side gears, this allows both wheels to get equal traction even though one is spinning faster than the other.
Is limited slip diff better?
A limited slip differential increases a car’s power and speed by utilising engine power more efficiently, thus allowing for a smoother and more enjoyable drive. Even on standard roads, LSD units can help prevent slippage and spinouts for near-perfect traction that translates to a safer and smoother ride.
How do I know my differential type?
The most accurate differential identification is provided by the bottom line of the tag number or axle tube stamp. Differential tags can easily be used to identify Dana and Ford differentials.
What type of differential do I have?
The easiest way to tell if you have an open differential is to jack up the car and spin one of the rear tires. If the other wheel spins in the opposite direction, you have an open differential. If it spins in the same direction, you have a limited slip differential, or LSD.
What is a BMW diff?
The M Differential The drive torque is transmitted from the engine via the transmission and drive shaft to the rear axle differential. The M Differential distributes the drive torque evenly to both rear wheels and compensates for the rotational speed difference.
What are the three types of differentials?
There are four common types of differentials on the market – open, locking, limited-slip and torque-vectoring.
Is AWD better than RWD BMW?
An RWD has superior braking performance because the weight is distributed among all four wheels. Traction is also enhanced as weight is moved to the rear wheels with increased acceleration. As with any car there are some setbacks. AWD vehicles are heavier than ordinary cars.
What is a 2 way differential?
A 2-way differential will have the same limiting torque Trq d in both the forward and reverse directions. This means the differential will provide some level of limiting action under engine braking. A 1-way differential will provide its limiting action in only one direction.
What is BMW M Sport differential?
The M Differential. It compensates for different rotational speeds of the rear wheels, particularly on curves. The inner curve wheel covers less distance than the outer curve wheel, meaning the outer wheel turns faster when cornering.
Is AWD a limited slip?
Sometimes there is a switch or level to turn off the AWD, but unlike 4WD they are perfectly at home on dry pavement while sending power to both axles. This is accomplished with a center differential, and often one that operates with limited slip properties.
How can I tell if I have a limited slip differential FWD?
If both tires spin in the same direction, you have limited slip. If the other tire spins in the opposite direction, you have open differential.
Is a locked diff good in snow?
Locking your differential can help maintain power to each wheel evenly, allowing the tire with traction to keep moving you forward. When you are driving on a road that is covered by snow regardless of the depth or if the road is icy and slippery, limiting the slip is always the best option for you and your vehicle.
Can you put a locker in a limited-slip?
The Powertrax lockers will also work in both open and limited-slip differentials.
Is limited-slip better in snow?
The limited-slip differential was conceived to improve motor vehicle mobility in situations where the traction conditions are not the same for both driving wheels. More driving force is directed to the wheel having the better traction to improve the ability of the vehicle to pull out of mud or snow.
Can you do a burnout with a limited slip differential?
So going back to your question yes it is possible to perform a burnout with a limited slip differential and infect it would be a better burnout as both drive wheels would be getting equal amounts of power, it will prevent you spinning up just one single wheel and looking like an amateur.
Can you do a burnout with an open diff?
yes you can if the engine has enough power. you can even do a burn out with a peg leg diff as long as the engine has enough power .
Do both wheels spin with limited slip?
In a limited slip differential, most famously GM’s Positraction, both wheels should spin during hard acceleration. For little off the line chirps, the wheel with the least amount of traction will be the one burning out.
How do I know what rear end I have?
To figure out exactly what axle you have, you can look for the Dana stamped bill of materials number. This stamped number can usually be found on the righthand side or on the longer axletube on the same side of the tube as the differential cover, facing the rear of the truck.
How do I know if I have a G80 differential?
In order to tell if you have a G80 differential, you’ll need to refer to the SPID label, which is an RPO code list sticker located in the glovebox. The Service Parts Identification (SPID) label will tell you plenty of important information about your vehicle, including if it has a G80 differential.
What is the most common type of differential?
Open Differential: This gearing arrangement makes up the open type differential, and is the most common type of automotive differential from which more complicated systems are derived.
Do all cars have limited slip differential?
Though all cars have a differential, only some have a “limited-slip” differential, which is the difference between being able to keep, or even have, traction when conditions are slippery, such as in mud, rain, or snow and ice.
