ID-ing springs
 

I was wondering if anyone could ID my old springs. They are solid blue with no markings and an inch or so shorter than the Racing Beat springs. I have no idea how long ago they were installed except that it would have been at least 3-4yrs (probably older.) A search suggested they might be TMC or ST. I'd just like to know what the previous setup was.

Those appear to be the same as my springs. They were on the car when I bought it, and only recently did I find the label that says "Suspension ____niques".....
I assume it used to have letters where the blank spot is, before that spot spent several years against the lower spring perch.
Given those facts, I'd guess at those being an older set of ST, like mine.

newer ST are black, MAY be older ST. look for any markings you can find.
