Hi all, I've had my car lowered and ever since the back end wobbles when driving slow. Mechanics have told me everything is straight, no damage, wheels and tyres fine too. Been told to get 4 wheel alignment done as bumped a kerb (Rear wheel) not long before it. Had new rear discs (which include bearings) too. They tell me that due to the car being lowered and the rear axle not being independent that the car will wobble side to side naturally as that's just how they all are. The car doesn't drive smooth at all when slow, is this normal then??
