The spring rate must increase enough to give improvement without causing undue harshness.\u003c\/p\u003e\n\n\u003cp\u003eSHOCK ABSORBER CONTROL - The shock absorber obviously plays a vital role in controlling a vehicle's stability. Excessive spring rate can often find shock absorbers struggling to control the vehicle (lack of rebound control).\u003c\/p\u003e\n\n\u003cp\u003eSPRING ENTRAPMENT - When an increase in spring rate and decrease in vehicle ride height is required, spring entrapment can become a problem. Previously, the only solution is a compromise of minimal increase in spring rate and\/or minimal decrease in vehicle ride height giving unsatisfactory results (suspension bottoming or not low enough).\u003c\/p\u003e\n\n\u003cp\u003eENTER THE SUPERIOR TAPERED WIRE \/ PROGRESSIVE RATE COIL SPRINGS\u003c\/p\u003e\n\n\u003cp\u003eProgressive rate springs are the ultimate in spring design. The principle is simple. The spring rate increases when you need it (cornering, load-carrying etc.) and decreases when you don't. The science behind designing a progressive rate coil is knowing over what suspension travel and to what degree the spring rate will increase. This varies greatly between vehicles. Referring to the above 3 conditions with Superior Engineering Tapered Wire \/ Performance Progressive Rate Springs a substantial spring rate increase is achieved with minimal loss of ride comfort as the spring rate increases and decreases where necessary. As the spring de-rates (the spring rate decreases) the shock absorber no longer struggles for rebound control and gives improved vehicle stability.\u003c\/p\u003e\n\n\u003cp\u003eWith \u003cspan style=\"font-size: 13px;\"\u003eSuperior Engineering\u003c\/span\u003e's Tapered Wire \/ Progressive Rate Coil Springs, spring entrapment problems are now often solved with substantial spring rate increases and ride height decreases available.\u003c\/p\u003e\n\n\u003chr\u003e\n\u003cp\u003eSUPERIOR SPRINGS PERFORMANCE TAPERED WIRE \/ PROGRESSIVE RATE COIL SPRING\u003cbr\u003e\n\"The Intelligent Coil Spring\"\u003c\/p\u003e\n\n\u003chr\u003e\n\u003cp\u003eProgressive Rate Design Principles\u003c\/p\u003e\n\n\u003cp\u003eRemembering the principle, 'the fewer coils in a spring, the higher the spring rate' as the spring compresses under load the gathered coils come into contact and become inactive thus increasing the spring rate. The point at which each coil comes into contact and the rate of increase is the result of extensive research, development and testing on advanced testing equipment.\u003c\/p\u003e\n\n\u003cp\u003eDe-Rate\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 13px;\"\u003eSuperior Engineering\u003c\/span\u003e's Tapered Wire \/ Progressive Rate Springs in most cases are designed around the De-rate principle, i.e.; the critical part of the suspension travel from ride height back to full suspension drop.
