The H&R 50424-88 is a complete front and rear set of race lowering springs for the 1992–1998 BMW E36 325i, 325is, 328i, and 328is. These are the most aggressive springs in H&R's E36 lineup, dropping the car roughly 2.0 inches in front and 1.3 inches in back. That lower ride height brings the center of gravity down and limits body roll, which is the main reason to choose them over stock or the milder H&R sport springs. Expect a firmer, less compliant ride, so these suit a dedicated track or autocross car better than a daily driver.
Fitment is limited to non-convertible E36 models built after 6/22/92, and buyers of 328i and 328is variants should confirm the match with a vehicle selector before ordering. Because the springs are shorter than stock, owners on user forums recommend pairing them with performance shocks or struts and E36 bump stops, since the reduced suspension travel can cause bottoming out. Searches for E36 race springs, 325is track lowering springs, and 328is 2-inch drop setups usually lead to this exact part number, so confirm the application before buying.
No. The application is limited to non-convertible E36 models built after 6/22/92, so convertibles and earlier cars are not covered.
Performance shocks or struts are recommended. Owners on user forums report that the shorter springs reduce suspension travel, so E36 bump stops are commonly added to prevent bottoming out.
Owners on user forums describe the race springs as considerably stiffer and harsher on the street. Those who drive mostly on public roads often choose the H&R sport or OE sport springs instead.
Installation is a manageable DIY job for someone with spring compressor experience, and owners on user forums describe it as fairly straightforward. Use a spring compressor to remove the stock springs, and replace the lower spring pads if they are worn. Because these springs are shorter than stock, the strut may feel loose before the car is lowered; owners on user forums say this is normal, so make sure the upper and lower perches seat correctly as you lower the vehicle to the ground. Check for bump stop clearance and a proper camber alignment after installation, since lowering can change alignment settings.
