I'm finally having my koni yellows and h-sport springs installed on Thursday and had a question. Once they are on the car, only the front's stiffness can be adjusted correct? And the rears must be taken out to be adjusted? Is there anything one can do so that you can adjust both without having to take any of them out? I'm pretty clueless when it comes to suspension stuff, so thanks guys!

 

You can make a "cut-out" in the trunk, but I wouldn't recommend that!!
Set the back to medium stiffness, should be OK I think...then adjust the front so that the rides handles well!! If it's too stiff/soft, you will have to remove them at the back...but that takes only a few minutes...
