Ok, I need to adjust my rear damping on my Tein CS TODAY. I just took apart my whole trunk but can't seem to find where the adjustments can be made. Up front it is obvious, but in the rear it is hidden. How do you get to the rears so they can be adjusted? I need help ASAP so I can take a trip!

 

You'll have to actually take the shocks out and adjust em that way. PITA I know.

 

i thought someone actually drilled a hole though the rear tower area to
get access for EDFC?

 

The fastest way is to just pull your rear shocks and do your change. I did drill my shock towers to set up my EDFC. In your case I would try 12 to 14 clicks from the softest setting.
The back end will get real sloppy at high speeds (over 100mph) if set to soft.

 

I went for 285s in the rear after my 275s wore out, now I buzz my left rear fender when I hit bumps or make hard turns with passengers or luggage. I am assuming that somehow dampning is set too soft on the left rear only. When it was installed the dampning was left the same straight out of the box, but perhaps they were accidentally set different from the factory or more likely got turned during the installation. Now I need to take off both rears to dial them into the correct setting. This poses another question, will I need to get another realignment since I will be taking out the shocks and puttting them back on?

 

Pasta, do you have any pics on how you drilled your shock towers for the EDFC? If so, I would love to see them. So is it possible to install the EDFC without removing anything as long as you drill out the rears? This may save me some time and money.

 

Installing the EDFC is a royal pain in the azz. I would not install it again if I knew it was that much work. I did not take any pictures, IM real happy with the ride I have with the CS setup.
There is 16 setting's with the CS coil overs. You will have to pull out your shocks to install the EDFC units and drill about a 1" hole to get the connectors to fit in the rear. Running the wires is a pain if you want to do the install right. I would set your CS frt. 12 clicks from soft and the back 14 clicks from soft. You should be fine with your alignment if you do not change your ride height. To be honest about the EDFC IM never sure if it even works half the time. Remember to check your tire pressure's and try to keep them the same so any changes you make to the shocks, you will know what is working. Your ride height will impact many of your settings so understand that a big drop will make your setting way more difficult to adjust.
IM running 19" volks with 275 in the rear and the 14 clicks did the trick.
