These HKS coilovers are like new I just purchased them brand new in March 2016 and have put less than 500 miles on them. I can show my transaction receipt if necessary. There like new the rear collars will have marks because i did make ride height adjustments. The coilovers are preset from HKS to yield a 3/4" drop but i did have to adjust the rears because it was to low for my Infiniti G37
These actually are made for the Nissan 370z
