At first after some searching, I thought the only difference between the two was that the SS included pillowball mounts and are dampening adjustible buuuuttt....
, this website from tein list what springs come with each kit.
As you can see they list two different springs for the basic and the SS's (front), then using this link Click it...
, using set springs, the SS spring is shorter than the basic by 1 in.
Is this correct, typo? Does this mean the SS can go lower (front) than the Basic's?
