~ Available in 6, 8, 10 and 12KG ~ 180mm length, 61mm ID ~ New High Tensile Alloy made in Japan ~ Does not deform over time, or after full crush testing (this means you dont have to set ride height twice, since they dont sag) ~ Higher strength means we can use a smaller diameter and use less turns to wind the same KG rating as standard silicon steel springs ~ Feels smoother and softer because of its extremely linear design. ~ increased traction and suspension response ~ Gold coating ~ Now shipping with our MAX PRO coilovers (reducing the coilover kit the price from the Swift package by $150) ~ Available for sale individually to upgrade other coilovers $40ea.
On the SLL, yes. These 4 most common rates were quite an investment. And it does not seem worth it to invest the same money into something thats barely used. Also the higher the rate, the less stroke you are likely to use so a less linear spring may not hurt you as much the higher you go. We can do the standard spring up to 22 KG
Pro coilover dampers did not change to run the SLL spring in place of Swift. They are pretty similar springs as far as the damper is concerned. I think that changing springs from heavyweight not so linear to light weight and more linear spring with better stroke is a good way to improve any coilover out there.
