I just installed stance gr+pro last weekend..the rear is making noise both side.I went back and tighten everything up again,noise is still there,is there anyway I can get into the rear top nut on the coilover from the inside of the car.I know that I may need to cut into it but it's okay because I need to have access to the dampering anyways..and does anyone know what is causing the loud clunking noise?I contacted stance and they told me to make sure everything is tight,can't tighten anymore..I try already twice..they said that they are gonna send me two new pillow mount for the rear.but I would still like to know what is causing this noise.any help!
