Spring Selection Our Cup Kits come with 2 different available spring fitments. You can choose our Sport Cup Kit with comes with Race springs or our Touring Cup Kit that comes with Sport springs. The cost and fitment options are the same on both so it is simply your preference on which to go with. About Lowering Springs Aftermarket springs are commonly used to lower the ride height and to reduce body roll. This is also often done when upgrading to a larger wheel and tire package. Generally speaking, the stiffer the spring rates (the amount of resistance a spring is set for against compression), the softer the sway bar setting can be set in order to achieve a similarly flat cornering response. When trying to decide which lowering springs are right for you, your goal should not be to drop down the car as far as possible. In many cases, overly "slammed" cars may actually be illegal for road use and terrible performers. The ideal range of adjustment should be 0.5 to 2 inches using traditional lowering springs. Any lower, the height of the perch should be adjusted by using a ride-height adjustable coilover suspension.
