I have a used kw HAS kit. My car has about 8,8xx miles and I installed it after the break in maintenance (1,200 miles) so the springs have about 7xxx miles on them. Asking for 550, so cal pick up preferred but I can ship at buyers expense. Everything on my car is being reverted to stock so will most likely be available for pick up on Sunday or will be shipped on Monday. Thanks for ur interest
