Like the E36 before it, the shock towers on the E46 are a notoriously weak point. Under normal driving conditions with a stock suspension it is unlikely that you will ever have a problem. But a sport street or race suspension with firm springs much of the energy from pounding the road is transmitted to the thin sheet metal in the strut tower. This pounding will cause the tower to deform or even crack. These plates will help disperse the energy and save you from costly repairs in the future. Price is for the pair.
