Product Description

H&R part #29531 Sport Lowering Springs are engineered for classic BMW E21 3-Series models, specifically the 320i and 323i produced from 1978 through 1983. These springs lower the vehicle's ride height roughly 1.3 inches at both the front and rear, reducing the center of gravity to improve handling, tighten cornering response, and enhance the vehicle's street stance with a reduced fender gap.

Made from high-strength spring steel and crafted with a progressive coil design, these springs provide a firm yet compliant ride suitable for everyday driving and occasional spirited use. The shot-peened and block-set process ensures durability and consistent spring performance over time. This kit is ideal for BMW E21 owners seeking improved handling dynamics, a sharper visual profile, and a more engaging driving experience while retaining comfort for street use.
