hehehe~

I don't know why but everytime I lift up my car using a jack to do something, then release it back, the rear end of the car will be "highered" by 2". Then after taking it out for a drive it will settle again, what is wrong here?!

Thanks!

 

did u lower it with coilovers?

 

It's natural. Your suspension travels in an "ARC", not straight up and down. Ever notice the wheels are closer together when the suspension is at full extension?
When setting the car on the ground when the suspension is @ full extension the wheels are at their narrowest track and the tires touch the ground as such, not allowing the suspension to compress.
In order to achieve normal ride height, the suspension must be able to follow its natural arc which means that the track must be able to get wider as the car gets set on the ground. The only way to do this would be to set the car down on ice, allowing the track to increase as the suspension is loaded.

Taking it for a drive (or just moving the car back and forth for a bit)allows the wheels to turn, allowing the suspension to compress by not allowing the tires to bind the natural arc of the suspension travel. (Very important to do this if your setting the ride height/corner weight of your suspension).

 

when ur done lowering it, just release the e-brake and you'll notice the rear of your car will settle right away.

it's exactly what shawn said.

 

It was a fun thing to watch.

 

Because u need the suspension to settle in place. That's why. It's normal.
