The new RCE/GTWorx Trophy Cup coilovers are based on the Bilstein B14 PSS system, and offer pre-set damping, monotube shocks with inverted front struts, and adjustable ride height. While the standard B14 is an excellent street product that offers good ride quality and a moderate performance increase, it uses fairly soft progressive rate springs. This is not ideal for a car that might see occasional track/auto-x use, especially with sticky street tires.
The difference between standard Bilsteins and the GTWorx version are the spring rates and damping. The springs are 400 lb/in front and rear, which is firm, but not excessively stiff. We feel equal or higher rear rates are necessary for the 08+ Impreza due to the rear suspension motion ratio. Many other coilover companies continue to put softer rear springs on the "new" chassis which is a recipe for terminal understeer and will require an excessively large rear swaybar to provide good balance.
The standard B14 is a pretty soft damper that is not capable of handling higher spring rates, so the valving of the GTworx Trophy kit has been changed to suit the new springs. While there is no adjustment knob, this keeps the price much lower than a PSS10 for example, and the valving is excellent right out of the box. RCE and GTWorx have years of experience developing shocks for Subaru models, so it would be hard to improve on what they and Bilstein have come up with. Once installed, aligned, and corner balanced, there is no need for further adjustment, and the 'triple C" three-layer coating on the shock bodies ensures these will last for years under harsh conditions.
