Steeda's performance lowering springs improve the overall handling of the 2003 Cobra by lowering the center of gravity and reducing body roll and pitching motion. The reduced longitudinal pitch of the vehicle during heavy braking, due to the optimized spring calibration, improves the overall braking efficiency. The higher rate of the front springs reduces the amount of load transferred to the front tires. This causes the load on all four tires to be more evenly distributed providing additional traction to the rear tires. The additional gain in rear traction usually results in reduced braking distances.

The proportionate increase in spring rate also reduces body roll, which limits adverse suspension movement. This confines the suspension geometry to stay within parameters that enhance the tires contact patch relative to the road, The result is improved vehicle cornering and handling, because front and rear tire loading is more evenly distributed. Therefore, higher cornering limits can be achieved because the built in understeer characteristics are reduced and provide for a more neutral yet safe vehicle.
