differentials feature:
- All New bearings, seals, crush rings, and gaskets
- Drastic performance increases by getting the power to the
ground
- Race grade gear sets made from the best alloys
- Increased acceleration via improved traction coming out of
corners and lower gear ratios
- Upgraded percentage of lock up to suit your needs
- Optional Range of lock up from 25% to 75% with upgraded BMW
LSD,

Q: Why does your BMW need a
performance rear differential:
Short Answer:
Improved acceleration, traction, and stability potential; as why
all M-Series are so equipped.
Long answer in simple terms:
Standard open-type differentials, equipped in most non-M Series
only send power to one wheel at a time in all conditions.
A Limited Slip Differential is able to effectively split power
between both wheels at crucial moments (Note: This is by different
means in different brands. LSD Vs TBD... OEM, Kaaz, Quaife,
Tractive, Wavetrac ect).
When you launch your car from a stop, having the power continuously
sent to both wheels increases traction exponentially. You leave the
line with more power getting to the ground, and less power spinning
your wheels; this is dramatically faster.
When your vehicle is turning, the outside wheel is rotating faster
than the inside wheel; the inside tire is doing less work. The
vehicle wants to 'lean' on the outside tire more further increasing
it's load. While the outside wheel is forced to do more work the
inside has less traction and therefore, in an open differential,
the power wants to go to the wheel with the least amount of
resistance and its wasted spinning the inside wheel when cornering
hard.
Through various means, a LSD or TBD effectively splits power to
both wheels and can aid in powering the car forward coming out of
turns as both wheels are utilized most effectively.
When entering a corner, this balance of traction helps to increase
the stability of the car when coming in at high speed improving
confidence and safety. This leads to faster corner entrance
potential.
Choosing to also equip shorter gears means that your effective
acceleration is improved, at a varying compromise in top
speed.
