They are not all that wonderful. I had issues getting the correct front springs for my GTO vert. They gave me way too stiff springs which looked comical. I tried to help them understand the issue but the girl I had to keep dealing with did not have a clue. On the 3rd attempt I just insisted they provide hardtop springs since the hardtop vs convertible weight is essentially the same. I’m sure they are continuing to sell the wrong springs to GTO vert customers
