Hey everyone, bring this thread back from the dead!!

I need some help with my stance GR+ coilovers. I recently purchased a IS350, and it came with Stance GR+ coilovers, but the ride is sitting too low in the back, it rubs anytime i good over the smallest bumps. So I would like to adjust the ride height and while im at it I would also like to make it smoother (only in the rear). Now, Im a complete nembie with suspension or coilovers, but I have been doing a lot of research on different forums. I have a good idea of how to make adjustments, but before I touch my car I want to be absolutely certain of what I am doing, so please let me know if this is correct:
First, Im going to adjust for damping by rotating collar A counter-clockwise, im not sure how many revolutions I should do, so I'll do 2 complete revolutions and see how that rides. After I will rotate collar B counter-clockwise untill its very tightly sitting under collar A. Thats all for damping correct?
Second, I would like to adjust the ride height. Here I'm going to rotate collar C counter-clockwise untill its lose. After I will grab the entire threaded body and rotate counter-clockwise, which will spin up and out of the base of the coilover. I want to lift the car up half-an-inch, so I'll rotate 3-whole revolutions and see how that turns out. Does the process sound correct, for damping and height adjustment?
thanks for the help
