    Rattly Suspension

    After having my car lowered with eibachs and eibach blacks, it seems to round alot more rattly and clangy especially at the back.

    What are the main culprits to check for this? Maybe some WD40 treatment?

    Cheers lads.

    loud or soft rattling.

    i experienced loud rattling and knocking in turned out the spring had been fitted upside down so thats might be worth a check (problem is the droop stop doesnt sit right which causes the springs to knock together when cimpressed)

    other than that im not sure what else it could be, a few people have mentioned when lowered a beam which runs by the exhaust will fit occasionally again this might be something to look in to

    Any writting on the spings should be the right way up

    And if they are progressive rate springs the closely packed coils should be at the top when the car is on the ground

    One of my rear springs makes a hell of a clatter and until this day I still havent found the cause.

    Some ppl report the exhaust hitting on the rear beam after lowering - didnt help me,,,and no doubt it wont help u either.

    If u do find the cause - let us know as mine could be the same

    I'm having issues still with rattling at the back - and I know the problem. The metal bushings on the top of the dampers is too big and moves about on the bolt.

    I'm currently in discussions with Bilstein as to what can be done, probably going to end up changing the bolt by the look of it.
