Just bought the car, trying to fugure out what is on it.

90LX, and these are obviously the rear springs. I was hoping someone might know what that number/code would mean.

Thanks

They look like Stock *progressive* rear springs. How tall are they?

To the top of the spring, a stock spring is ~12.75". The "B" spring is 12". The part number for a "B" spring is E5SC-5560-AA

C are constant rate springs. B are progressive. That means that *all* of the coils have the same spacing for C springs. The B springs will have some coils (~3) closer. That way, those close coils go into "bind" around 50% compression and result in a higher rate spring.

So, by the looks and the height, I'd say they are B springs.
