Now, D2 hasnt been around a long time, only since 1997. They have a their coilover which is comparable to the Tein Flex since it has shock height adjustability to allow full travel (something like that). Without the pillowball mount i can get it for 930 shipped. Now do you think im asking for it by purchasing a Coilover like this? The Nissan owners have used it and like it a lot, and the company's racing team seems to have done well (dont know if that should even make a difference). You can get the spring rates custom tailored, and the coilovers have 32 levels of damping. so umm should i go with something like this or just get the tein ss?
