THe other set are rears, but they are warn out. These are coil overs while the others are not. I don't believe the two would be compatible. The Aldans are actually designed for the rear end that is in the car. The issue with this one it appears is that the top end somehow came unscrewed and pulled the last two threads. The other three appear to be fully threaded into the top cap and do not appear to be in danger of the same or similar failure. Not sure how this one got in such a condition, but all four were set to the same static height.. which should provide for sufficient expansion and contraction. With the 350 pound springs they do not expand and or contract easily.
