Steeda's newest springs for the 03 Cobra. These springs have a progresive rate of 720-780 in the front and 650-790 in the rear. Lowers the car approx 1 inch -1.5 inch. These springs are recommended for Cobra coupe owners looking for a big improvement in handling, can be used in convertibles but the ride quality is much stiffer than stock. These springs are also a good choice for 99 and 01 cobra owners who are looking for a big improvement in handling but don't mind a little stiffer ride. Note to all the convertible owners-the factory springs are much softer than a coupe, this is why the ride quality change is so noticable in your cars, compared to coupes.
