Eibach ERS 180-60-70 springs which correlates to 400# springs front and back. They are the original Superformance shocks/springs supplied on MKIII 2986, stated as being Bilsteins. They were absolutely perfect while on the car and have a total of just over 12,000 miles on them. Only reason I replaced them is because I got the upgrade bug and decided to do them while I was doing the R/T shock mounts, sway bars and ball joints.
