Rear axle lowers after damper change

Hey together, our moose has got 4 new dampers, from Kayaba. Feel great, pleasantly tight, but not too tight. So far, so Knut. However, the car has been standing about 60mm lower in the back since then, with the same rim and tyre size. What doesn’t even look so bad per se. But what happens under load, topic “looping on the wheel box”? And in front, the moose is still exactly as high as before the shock exchange. That looks funny. Just lay 30mm lower in the front, kla r, you could do that… Then it fits optically again. But I am curious. Can it be that the dampers of Kayaba simply have a different = shorter length? Or can you do something so thoroughly wrong when installing the car so that the result is lower? Please clarify 😉 Greetings, Volkersson
