I have recently purchased a set of tein ss coilovers. I want to install them myself but in the instructions it says that you need to modify one of the bushings if you are using the stock upper pillow ball mounts. Does anyone know how hard it is to do this? Or what exactly you have to modify? Any help would be appreciated, I just don't want to start a project I can't finish because the bushing is impossible to modify. Thanks

 

Most likely it involves grinding/drilling out the bushing to accept the larger diameter damper rod. Other than that, I have no clue.

 

yes all you need to do is drill out the hole in the upper mounts. In stock form, the hole is shaped like the letter "D". you will ned to drill out the hole to make it a circle, that's it!
