The most popular spring in H&R's line-up Sport Springs will lower your vehicle an average of 1.5-2.0 inches for a lower center of gravity, improved handling and a more aggressive appearance. Sport springs feature a spring rate that is firmer than that of the OE Sport spring but is still comfortable enough for daily use. Sport springs are an excellent choice for street and occasional track use.
When combined with the Koni sport shocks you'll have the best ride and handling combo you can buy for your M3.
