The H&R 29824-2 is a full four-spring sport set for the E36 BMW 3 Series, covering 323i, 323is, 325i, 325is, 328i and 328is models in coupe and sedan body styles built after June 22, 1992. These German-made coil springs are designed to lower the car approximately 1.5 inches at the front and 1 inch at the rear, which tightens the fender gap and lowers the center of gravity for less body roll than stock springs provide. Owners on user forums describe the H&R sport rate as stiffer than OE, with noticeably better control in corners, while remaining comfortable for daily driving. Owners on user forums often pair them with Bilstein B8 or Koni dampers for a balanced street and autocross setup, and that combination is the most common reason buyers choose this kit over a cheaper lowering spring.
This is the non-convertible E36 kit, so fitment is specific: E36 325i, 325is, 328i and 328is coupes and sedans from the post-June 1992 production run. Convertibles require a different H&R set. Searches like "E36 325i sport springs 1992-1998," "H&R 29824-2 install," and "E36 328is lowering springs 1.5 front 1 rear" typically point to this exact application. Because the spring change affects ride height and suspension geometry, plan on a wheel alignment afterward and check that the car's current shock and strut condition is adequate before installing a lower spring rate.
No. This set is for non-convertible coupes and sedans. Convertible E36 models use a separate H&R sport spring kit, so confirm your body style before ordering.
Owners on user forums commonly run these springs with Bilstein B8 or Koni dampers and report better control. Owners also note that the springs ride firmer than stock, so worn dampers can feel unsettled after installation.
Owners on user forums recommend replacing the top mounts on all four corners during the swap, and report that the new mounts made a noticeable difference in ride quality.
Those figures are approximate. Actual ride height varies with the car's condition and whether it has the factory M Sport suspension, so confirm the exact numbers with the manufacturer.
This is an intermediate job. Front springs require a proper spring compressor on the strut assembly, and owners on user forums stress that compressed springs can release suddenly, so never rely on a jack alone. Rear coil swaps are simpler: support the rear hub with a trolley jack, secure the car on axle stands, and use an 18mm socket to remove the lower shock bolt. Owners recommend replacing the top mounts while the struts are apart, and checking the wheel alignment once the new springs are in.
