Where did you buy the Eibachs?

There's a sure fire way to check I they're correct bit it involves getting under the car again (and still having the box)

On the box will be the part number - E3588-140 hopefully. As well as that will be a code, not sure what it'll be but it's an internal part number, which SHOULD also be marked on the springs themselves.

If its labelled as an ST170 kit with the above part number, but the code on the springs doesn't match the box, they're wrong, simple as that.

I've had a look to find the code but I can't.

If you get the numbers off the springs and post them here, I can check them for you, should be 2 different numbers, 1 front, 1 rear.
