the adjustability was too much. like 4 whole revolutions. gaz did however provide a product testing chart for each 4 strutts that proved they were equal. its just say, a 360' turn on one strutt needed to be 520' on another. which i just dont have the patience to set up.
they did however re machine the collars as my eibach springs didnt fit. they then did fit anf they were cack. far too wallowy as they were progressively wound. i put this down to issues with set up as well.
