So an update. Jacked the car one more time. Couldn’t find anything wrong with the shocks or springs. There’s a bit of rust on the rear passenger spring, but nothing too terible. Looked for anything that may look bent or broken off and found nothing. The springs are 40mm. My friend said that if the car hadn’t been lowered that much and wasn’t on wheel spacers, i would never notice this. After some more measurements, the car sits about 2,5mm (1/5cm) lower on driver rear respectively. Could be the cars weight distribution. Maybe the gas tank is slightly more to the left. But in conclusion there doesn’t seem to be any faults in the rear coils and shocks. However the structural integrity of the coil is sometimes hard to diagnose, so i think i will be changing all four coils in the upcoming months, probably a bit before summer. Maybe make the car sit a bit higher 😅
