Do you have to add weight to the car?

No. Not needed until alignment is performed and a shop with experience in aligning will know where to put it and how much

Ok we had one in and I dont think they added weight to it. Because you could push up the strut and it would come up about 3 inches or so I do alignments all day and I am not a audi technican or ever heard of this. Thanks so much.
