  • 250 lb Front Springs

    These are the 2.25" ID Springs for the wide track. They won't work on the narrow track.

    Including the top collars.

    The adjustable lower collars have 2.25" on one side and 1.90 on the other so if you have these and the wide track they should fit.

    Made for Caterham by Eibach.

    A reasonable upgrade for a car used on the street and track.

    Uncompressed length is 7" and could fit other applications. These are a standard size Eibach spring.

    $100 the pair OBO. 805-402-1225

    Doug, What are the stock springs rated?

      I think they are ~175 lbs but will have to check.

      There are spring rate calcuators on the internet that are quite accurate.

      I just sent you a spreadsheet to do the same thing.

      I got this from Richard, see instructions.doc

      My 250 lb Eibach springs calcualted to 242 using this spreadsheet and I may not have counted the active coils accurately. You should count partial coils too.
