Reduce weight and increase front end rigidity on your S550 and S650 Mustang with a K-Member from BMR's suspension! Stock K-members are heavy and bulky, slowing performance on the street and track. BMRs Street K-Member (KM760) weighs only 50 pounds with the factory motor mounts and is designed for street performance, drag racing, and handling applications. When performance is a must, rely on BMR's suspension!
