IDK, still learning. That's what I observed. I think it may be due to the shedding of load, reduced hindrance to forward motion. Cylinder around 50 kg, other parts around like kit and pipes etc 6 to 7 kg, and the metal frame was 11 kg. Almost like one more person in a car.
I was afraid the car might jump more because of the springs might have a release of load, it has but not to a great extent.
