I am looking for the parts I need to convert my Tein SS coilovers set. The set I have installed use the stock top hats.. I am looking for the parts to convert them to the Tein Pillowball mounts so I can use the EDFC.. I know now that I need all new spring seats, pillowball mounts, collar, and nuts for the top. I am still not sure what I need for the rear.
