I have never done this before. I have heard that adjusting coilovers is not that hard but for whatever reason the spring perches will not turn at all. It's like they are rusted together but they're not. I have tried using a pipe on the end of the wrench, but that didnt work. i thought there might be some kind of set screw or something but NOPE! anyway, i bent both my wrenches trying to break the dang things loose and it just wont move . Any ideas?
