BMW M Performance suspension kit
With the M Performance suspension, your BMW 3 Series experience becomes even more unique. The shock absorbers have been extensively tested and coordinated using strict motorsport criteria. The result is even more dynamic driving that will amaze on every straight and every corner. (For vehicles without M Sport Package & M Sport Suspension, options 337A & 704A, front and rear stabilizer bars, oem part#'s 33556853474 & 31356792125, are required for installation.)
Waiting to hear confirmation from BMW Canada before I buy more parts. They insisted previously that I wouldn't need anything else.
