What's up guys.

I just acquired some PSM/PBM Coilovers from UpGarage, and I have a few questions on how to get these coilovers setup back to PBM Recommend specs, as from me eyeballing it, it seems that someone have played around with the specs a little bit.

I have sent a message to PBM for diagrams and etc, but I figured that I would get a quicker response here.

1) How do I exactly set the preload back to zero? one of the front coilovers look like it has less spring travel than the other. Same for one of the rears. What is the PBM factory length and Preload length/specs?

2) Does anyone have any pictures, instructions and diagram for how the coilovers is suppose to be installed properly?

and does anyone know what is the front camber of these coilovers?

Thank you!

The previous owner probably had the car corner balanced, the would explain why the perches are in different positions.

I would just preload them all about 5 turns just to keep the spring firmly seated between the perches. Or you could follow the advice posted by the Fortune Auto rep here: http://zilvia.net/f/showthread.php?t=587571
