The most popular spring in H&R's line-up Sport Springs will lower your vehicle's center of gravity, improving handling and adding 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. These Springs along with the combination of the Bilstein Sport Shocks offer the customer great balance between ride & handling. A balance that most aggressive driver's will appreciate.
