i dont know the brand of the coilover but my car is tooo low i must be stupid cause I cannot figure out how to raise my car up on these things.
I wish these came with instructions.Can someone tell me how to do this, My front tires rub BADLY

 

to make it easier pull the wheel off. you will see 2 rings on the threaded sleeve. if they arelocked together as they should be, you have to move them together to unlock.....the top ring , turn in a loosening motion, and the bottom turn in a tightening motion. they should unlock. then move the top ring all the to the top of the threads ( raising the car ), and repeat with the bottom. put the wheel back on the car and see if the height is where you want it. if not turn the rings down to desired ride height.

 

^1 could not say it any better man.
