Rear coilovers settings
 

Hi Guys,
I cannot find answer on the forum, so sorry if there is any and I cannot find it ;)
I'm a happy owner of Tein Street Flex coilovers. My mechanic's service has already installed all 4 coils in my Lancer about half year ago. But to be honest with you guys - I have no idea how to set rear coilovers damping forces? Front coilovers are easy to set but how to get to the needle valve on rear coils? Have you got any pictures/solutions to get it works :) ?
