Allot of sport cars don't come with an LSD or any other type of locking differential.
For Example: An older model Z4 3.0i, pretty fast sports car. No LSD, shame because one would make it much better.
One of the few lighter/slower sports cars I know to have one right now is the Toyota GT86, in contrary to the BRZ who doesn't have one...
It was way more common in the past to have an LSD as an option orso when you bought a new car (RWD that is). Older BMW's, Toyota's etc..
