Maaan these things are sooo bouncy in the rear, I have the OEM setup, and i hv the damping on the middle setting in the rear. ive adjusted the preload several time on the spring bucket. the strut says its the height adjustment part.. so i dont jack with dat anymore cus it the height i want. so i quess the problem is either the preload or damping, imma noob so its a learning process.. goin over speed bump feel like my car fell out of the sky lol. please help

 

If I remember right the spring adjusts the height not the shock..

 

i thought so too, i know the BCs work like dat, but on rear struts is say " for height adjustment use strut only", the spring in the bucket is for preload

 

Hmm.. I know the stances I did I had to adjust the spring for height and jack up to spring so it gets tension and measure from the top to bottom mount on the car for the strut and adjust it..

 

well ive adjusted the preload (spring) several times and it never changed the ride height of the car

 

How fast are you going over the speed bumps? Although my car couldn't really get over speed bumps, it definitely didn't "fly" up going over bumps. Even though my front preload was a bit off, my back was fine just using the standard spring height set, jack up spring bucket a tiny bit, adjust shock length procedure. Dampening didn't really adjust the ride all that much.
