BMW E9x 325/328/330 MFactory Limited Slip Differential
A lesser known feature of the highest caliber performance cars has nothing to do with engine power output, suspension dynamics, or build materials.
Almost every truly distinguished European sports car utilizes a limited-slip style differential.
While an open differential effectively accomplishes the task of allowing one wheel to spin faster than the other around corners, during power delivery, this behavior is not always desirable.
