Unveiling the Superior Suspension Linear vs. Progressive Springs

A progressive spring is preferred for street use because its soft initial rate allows it to compress more vs. a linear spring (w/ a similar avg. rate) for the ... linear means the spring rate is constant (e.g. 100 lbs/inch for each and every inch of compression, so that it would take 300 lbs to compress ... on a linear spring, the spring rate is constant, so to compress the first inch of the spring takes 225, as does the last inch. on a progressive ... Linear springs: · 1.The automaker has the luxury of designing the strut, tower, and suspension geometry around their spring and shock. · 2. Similar to progressive rate springs, variable pitch springs are different than regular compression springs that are designed to have a linear spring rate. if there are some coils really close together that collapse as the spring is compressed, that is progressive. if the coils are evenly spaced, it ... Linear spring in one and progressive in the other. On the street, The linear spring is better in corners, less body roll, much easier to regain ... Taken from Silvia.net forum - Linear springs are the same spring rate no matter how much they are compressed (preloaded). With progressive ... But as shown in the picture for the progressive spring (variation in the outer diameter and the distance between windings) the reaction force still stays linear ... DSC is installed, and will be tuned once the spring situation is sorted and the coils installed/corner balanced. Car will see mountain/canyon ...
