What Is Progressive Suspension? In A Normal Spring, The Coils Are Evenly Spaced And Compress At The Same Rate. For Example, If You Have A Spring That Has Ten Coils Spaced A Centimeter Apart, And You Push Down One Centimeter On The Spring, The Entire Spring Compresses One Centimeter And Each Coil Will Then Be 0.9 Centimeter Apart In A Two-Step Linear Spring (Or One-Step Progressive), About Half The Coils Have Shorter Spacing. As The Spring Compresses, The Coils Move Closer. At A Certain Point, The Shorter Spaced Coils Touch, Effectively Eliminating Them From The Spring. You Then Have A Spring Comprised Of Only The Longer Coils. This "Second-Step" Spring Will Be Much Stiffer Than The Whole Spring (The More Coils, The Easier It Is To Compress The Spring). The Result Is That You Have One Set Of Handling Characteristics Before The Shorter Coils Touch And Then You Have Another, Completely Different, Level Of Response After They Touch Giving You The "Perfect World" Is What Hyperpro Is All About. Each Coil Is Spaced Differently So As The Spring Compresses And Releases, It'S Characteristics Constantly Change. When The Spring Is At Rest All It'S Coils Are Available And It Takes Very Little Force For The Spring To Compress. As More Force Is Added, More Coils Start To Touch Making The Spring Stiffer. The More The Force, The Stiffer The Spring. The Result Is A Perfect Setup In Any Situation The Benefits Of A Progressive Suspension Are Almost Too Numerous To Mention. Since The Effectiveness Of Your Suspension Affects Braking, Handling, Comfort Safety And Even Lap Times. Hyperpro'S Progressive Springs Give You A Fantastic Range Of Benefits.
