I was just wondering wutz the difference between Tein ss and Tein Flex other than the flex is is compatible with the EDFC??? Everything else sounds same to me.

Higher spring rates, better dampers, independent height adjustment, pillowballs/camber plates (unless you get Tein SS-P).

If you don't know how to use the flex, then don't get them. There is no need for the flex unless you are racing.

Flex cost alot more too, Tein SS is also EDFC compatible....I'm thinking about buying it for my Tein SS.

Read Tein's website. It tells you the features of both.
