    Big problems shock absorbers Bilstein B6

    Sorry to start a new thread about Bilsteins again but im in urgent need of help. I have fitted one Bilstein B6 shock with OEM spring and the ride height increased. After closer inspection it seems i had the lower spring seat the wrong way around. The problem is, when i turned the spring seat to the right way and put everything back togather, the spring is now loose on the shock absorber when i undo the spring compressors. I bought these shock absorbers on the impression that i could use the OEM springs but the spring is too short when fully extended.

    Is there anybody that is using OEM springs with these Bilstein B6 shock absorbers?

    Pics might help?

    Just to clarify you are removing the whole top mount, shock and Spring assembly from the car to swap over the new shocks?

    If so are you saying with the spring on the seat and the top mount on and retaining top nut done up the spring is slack.

    Yes, exactly that. When reassembled the spring is loose. These are standard springs and ive double checked the part numbers and the shocks are the right part. The only way i can get the spring to sit firmly is by turning the lower mounting seat upside down but then the ride height is too high (as i complained yesterday) and the spring then does not sit properly on the mount.

    If the spring is loose its no big deal, when you have 1700 kilos of car on it, it will be fine
    I would gladly pay you £10 to never log onto this forum again, and I am serious. Scott M

    I did think this and hopefully the shock absorber should never fully extend during driving unless im doing jumps? Ill just have to make sure that if i jack the car up in future that the spring does not turn relative to the mounts otherwise it wont seat correctly. Ill send Bilstein an email and see what they say.

    The spring should never be loose. It will fail an MOT like that as is not road worthy.

    So whats the remedy? The website clearly says you can use stock springs with the B6 shocks. They have some minor scratches on them now from fitting so i cant send them back and i cant buy lowering springs because the car wont go in the garage.

    Is there anybody on here using stock springs with these shocks?

    My mates used to cable tie them back in the day (when they used to cut the springs to lower their cars!)

    On an mot test, the front and rear are lifted off the floor independently. And items such as springs, shocks and top mounts are checked. If the spring is loose its not safe. This why some top end suspension has two springs. One as the main coil spring and a then a ‘helper’ spring which is used to take up the slack and keep the springs correctly seated when the wheels are off the floor

    Ah got you, I just can't imagine once fitted its loose even on the fully suspension drop, but it's really not easy to picture and something sounds odd re this.

    In my experience there is not much compression in the springs once off the car, ie you don't need compressors to reattach the shock top bolt and I've certainly never lifted back in a shock spring and top mount that's had a loose Spring, somethings not quite adding up?

    Both supra’s i have owned have had aftermarket suspension so cannot comment on the standard spring compression. Pictures mean a 1000 words abd we need pics

    I dont have pics as i didnt take any. Will have to get some tomorrow but just imagine the strut all built up as per normal and the spring not long enough to touch the top and bottom mount at the same time. Theres a gap of about 5-10 mm between the spring and seat, the spring is not under any tension at all.
