    mot failure?

    a friend of mine told me that fitting lowering springs with standard shocks can be a mot failure. he said that when they jack the car up the spring can move or be moved by hand and will fail for allingment.

    talking about the front.

    is this true?

    not entirely true, if the spring moves, its not fitted correctly.

    General rule is anything lower than 40mm drop, you should use more suitable shockers.

    If fitted properly and still complete it will not fail.

    Rear springs usually fail on broken pigtails...tight curly ends being broken.

    Yes its true to an extent.
    Standard dampers are quite long when fully extended, so when the rear axle is allowed to fully drop down and the dampers extend, short springs can come dislocated....
    Uprated dampers are shorter than standard so stop that from happening by restricting how far the axle can drop down.....

    I had an MOT last weekend, when he went under the car he used a jack to test everything on the back axel, when he lowered it back down he couldnt get the jack out cause my car was too low!! Haha he had to get a mate to lift the car - which didnt work, they drove it off in th end.

    You will be fine unless the springs are mega short.

    Years ago I had 50mm lowering springs on my Corsa with standard dampers. I received an advisory for the springs being loose when jacked up but not a fail.
