*Original upper links were made to deflect under load, a bad thing for good handling and traction(in of the the product images you can see where the stock 135/335i guide rod can deflect and bow under cornering and acceleration loads). See the difference between the stock 335i and M link in the second photo.

*Aluminum links are made of all aluminum, a lightweight component thereby reducing wear and tear on other, more critical parts (rear subframe, control arm bushings, etc) Each link weighs just over 1.7 lbs making for a total of ~3.4 lbs for both parts (stock guide link weigh 2.5 lbs each or 5 lbs for both). A weight savings of over 1.5 lbs from the rear suspension.
