The ones that a few of us have installed are the FK vectra b and the rears bolt up fine but the fronts are a massacre. The fronts have an issue with making a lot of sounds, the stud on the strut that bolts into the strut mount is smaller then the OE size. It has room to move around and rub in the strut mount so that's the current issue. Also the spring hats ( spring seats ) do not fit together with the thrust bearing and that means metal on metal, for a perfect fitment you need to modify or make custom spring seats that work on the OD of the coil and fit into the strut mount with the thrust bearing. Do you have a pic of the ones you got?
